Nextcloud seems to have a bad reputation around here regarding performance. It never really bothered me, but when a comment on a post here yesterday talked about huge speed gains to be had with Postgres, I got curious and spent a few hours researching and tweaking my setup.

I thought I’d write up what I learned and maybe others can jump in with their insights to make this a good general overview.

To note, my installation initially started out with this docker compose stack from the official nextcloud docker images (as opposed to the AIO image or a source installation.) I run this behind an NGINX reverse proxy.

Improvements

Migrate DB to Postgres

What I did first is migrate from maridb to postgres, roughly following the blog post I linked above. I didn’t do any benchmarking, but page loads felt a little faster after that (but a far cry from the “way way faster” claims I’d read.)

Here's my process
  • add postgres container to compose file like so. I named mine “postgres”, added a “postgres” volume, and added it to depends_on for app and cron
  • run migration command from nextcloud app container like any other occ command. The migration process stopped with an error for a deactivated app so I completely removed it, dropped the postgres tables and started migration again and it went through. after migration, check admin settings/system to make sure Nextcloud is now using postgres. ./occ db:convert-type --password $POSTGRES_PASSWORD --all-apps pgsql $POSTGRES_USER postgres $POSTGRES_DB
  • remove old “db” container and volume and all references to it from compose file and run docker compose up -d --remove-orphans

Redis over Sockets

I followed above guide for connecting to Redis with sockets with details as stated below. This improved performance quite significantly. Very fast loads for files, calendar, etc. I haven’t yet changed the postgres connection over to sockets since the article spoke about minor improvements, but I might try this next.

Hints
  • the redis configuration (host, port, password, …) need to be set in config/config.php, as well as config/redis.config.php
  • the cron container needs to receive the same /etc/localtime and /etc/timezone volumes the app container did, as well as the volumes_from: tmp

EDIT Postgres over Sockets

I’m now connecting to Postgres over sockets as well, which gave another pretty significant speed bump. When looking at developer tools in Firefox, the dashboard now finishes loading in half the time it did before the change; just over 6s. I followed the same blog article I did for Redis.

Steps
  • in the compose file, for the db container: add volumes /etc/localtime and /etc/timezone; add user: "70:33"; add command: postgres -c unix_socket_directories='/var/run/postgresql/,/tmp/docker/'; add tmp container to volumes_from and depends_on
  • in nextcloud config.php, replace 'dbhost' => 'postgres', with 'dbhost' => '/tmp/docker/',

Outlook

What have you done to improve your instance’s performance? Do you know good articles to share? I’m happy to edit this post to include any insights and make this a good source of information regarding Nextcloud performance.

Since i started using nixos i don’t have any problems with nextcloud 🙃

I only recently started using nix and NixOS. How’s the update process for nextcloud? Can you use the self updater?

In nixos you almost never use any “self” thing

You update everything with your whole system at once

Even the installed apps, the true nixos way to install them is through the configuration file

That makes sense, it does sound better to keep it within nixos! I’ve mostly been using nixos to bootstrap servers that run nomad+docker, so beyond the system-level config, I haven’t done a lot with additional software yet.

Heads up, you can also get postgress to use a socket and mount that through for another speedup if you haven’t already

Have you tried the AIO method that’s now the primary supported docker install?

It’s really good, and I’ve set up and used NC in a variety of ways since about version 7.

im not sure / cannot recall. it’s been a few months since i last tried to install it and it kept erroring out. im definitely strongly considering looking back into it though, it’s just that reverse proxying to the container was a nightmare… it still haunts my config, lol

I use NPM and all I think I had to add to it was

client_body_buffer_size 512k;
proxy_read_timeout 86400s;
client_max_body_size 0;

in the Advanced config. I’d love to move to Traefik but I could not figure out how to make that work.

There were some other gotchas. If you run into something, ping me, I might remember if I encountered it and what I did.

My advice: use the nextcloud snap package. It’s seamless.

@4am@lemm.ee

It is, in fact, the only Snap I’ve ever used which worked without issues

That being said, it’s kinda slow in some cases, but perfectly useable nonetheless

I know snap isn’t popular among Linux nerds, but I was really having issues with the AIO docker setup and at the time I didn’t have the time to troubleshoot/fight it. I needed to give my family a file drop link to share photos for a memorial service.

I figured, the snap package was recommended on their site, maybe it won’t be horrible. To my surprise it was incredibly easy, has been rock solid, never had performance issues, and it’s always up-to-date.

Snap may suck for some use-cases but this one seems to be right in it’s wheel house.

It also has an export/backup capability built in.

that is… surprising. not that i don’t believe you, snap just doesn’t have a good track record, lol. ill have to research if it’s feasible to run a snap package on a debian server, though.

I’m going to try this next week. My nextcloud instance is getting a bit sluggish lately.

I had been running Nextcloud on an old laptop using Ubuntu, but that machine died. I have a Windows PC originally built for gaming that I am considering using for Nextcloud. Anyone have any experience with NC and Windows? Thought on the DB switch on Windows?

100% agree with tofubi, Docker on Windows is a form of self-abuse, like cutting yourself. It’s a train wreck for anything other than a little bit of testing for development work. You will come away with a bad taste in your mouth about Docker, I avoided containers for years because I started with them on Windows docker.

I’ve run a lot of different scenarios with docker, what I’ve come down to as the cleanest and easiest to maintain is Debian 12 with the Docker convenience script. It’s fast, hassle free, and doesn’t have a bunch of layers of weirdness like using Ubuntu Server with a docker snap that makes troubleshooting a nightmare.

for anything other than a little bit of testing for development work.

It’s really awesome for development work, though. Visual Studio has built-in Docker support, so I can run my app and its unit tests on both Windows and Linux (via Docker) at the same time on the same system during development.

This sounds interesting.

I use docker in vscode for latex. It saves me the trouble of having to install texlive on my system. I have a task defined that mounts my sources in and runs the compilation in the container.

Would love to hear about your work flow.

I don’t think you’ll do yourself any favours setting it up on Windows directly. How about docker+wsl2?

“Way faster” came from me :D

It is the complete package which makes it way faster…

Postgres, Redis, PHP Opcache, general PHP tweaks ( PHP.ini, child processes etc, use calculator ), HTTP-2 instead of 1.1

For HTTP-2, you can add this for Apache in your vhost:

Protocols h2 h2c http/1.1

For example:

<VirtualHost *.80>
ServerAdmin admin@server.com
DocumentRoot /var/www/html/nextcloud/
ServerName my.domai.com
Protocols h2 h2c http/1.1

....

In NGNIX add this in a new line:

http2 on;

For example:

server {
  listen 80;
  listen [::]:80;
  server_name my.domain.com;
  http2 on;

....

Using NGINX over Apache did nothing for me, so I use Apache with PHP-FPM 8.3, because I am using it for Wordpress too, same for Redissockets. I would recommend not to use a docker container for Nextcloud. I don’t like it for Nextcloud and I don’t use docker for Wordpress. Docker has other use cases in my setup, but not those 2.

This is just my personal setup.

Maybe it can help someone :)

I’ve been a proponent here for a few months on using postgres/redis every time someone shits on NC for performance. While I agree the database change itself isn’t a huge improvement, it pays for itself long term in larger volume installs when you and your organization/group get using it heavily. The redis connected on socket like the AIO mastercontainer sets up is where the real juice comes from, but only on an install that gets used so it caches properly. The first time you fire it up, it’s pretty slow but as it gets used, things are much better.

Very anecdotally, I saw a little speed improvement but not all that much. DB size increased a bit. I’ll be sticking with it for the time being because why not.

Try MySQL instead of MariaDB. They have some performance tweaks in version 10 that aren’t present in MariaDB.

Also, tune your MySQL (or MariaDB) server. Make sure all tables use InnoDB. Enable the slow query log and analyze slow queries (there may be missing indices). If there’s a lot of unique queries, increase the query cache size.

The easy approach is to run MySQLTuner after the MySQL or MariaDB server has been up for at least a week, and go through its suggestions.

There shouldn’t be a significant difference in performance between PostgreSQL and MySQL/MariaDB if both have been optimized. Out-of-the-box config isn’t ideal for a production system.

Depends on how you’re using it. You can wrong an absolutely insane amount of performance out of postgres that you cannot with MySQL.

I wonder how much next cloud leaves on the table?

I wonder what performance impact there would be if you were to move pgsql onto bare metal with enough ram dedicated to caching all of the db data (think: i5 or i7 nuc). That’s going to be my next step with my homelab; I want to migrate everything to a single db host with a lot of RAM and M2 storage and avoid the db process replication I have going on. I have no performance complaints with NC currently, I’m running PHP cache and redis as well as image preview and imaginary.

Is there a way to self-host nextcloud by downloading one file, docker container, .nzb, .jpg, ANYTHING that includes all these parts and can just plug in and run? Is that a thing, or do all self-hosters spend every waking hour sudo updating?

You mean like the AIO image, the one officially supported way to install Nextcloud?

But if you want to tune it, I’m afraid you’ll have to run sudo tune once per waking hour.

Nextcloud AIO or all in one. It works relatively well. I run both my own container and an AIO instance and I’ve been pretty happy with it, I’ll likely migrate to it for my docker only one in the near future. Nextcloud AIO

I didn’t think Nextcloud AIO would actually work with existing files on a separate drive. I know it says it will … but … I’m not interested in buying a gigantic new harddrive to clone all my data to just to run one program.

Also, if it’s running in WSL or a VirtualBox VM it would be fucking hell to get it to play nice with the network.
