# Optimise your installation
|
|
||||||
|
|
||||||
Now that you have Dendrite running, the following tweaks will improve the reliability
|
|
||||||
and performance of your installation.
|
|
||||||
|
|
||||||
## File descriptor limit
|
|
||||||
|
|
||||||
Most platforms have a limit on how many file descriptors a single process can open. All
|
|
||||||
connections made by Dendrite consume file descriptors — this includes database connections
|
|
||||||
and network requests to remote homeservers. When participating in large federated rooms
|
|
||||||
where Dendrite must talk to many remote servers, it is often very easy to exhaust default
|
|
||||||
limits which are quite low.
|
|
||||||
|
|
||||||
We currently recommend setting the file descriptor limit to 65535 to avoid such
|
|
||||||
issues. Dendrite will log immediately after startup if the file descriptor limit is too low:
|
|
||||||
|
|
||||||
```
|
|
||||||
level=warning msg="IMPORTANT: Process file descriptor limit is currently 1024, it is recommended to raise the limit for Dendrite to at least 65535 to avoid issues"
|
|
||||||
```
|
|
||||||
|
|
||||||
UNIX systems have two limits: a hard limit and a soft limit. You can view the soft limit
|
|
||||||
by running `ulimit -Sn` and the hard limit with `ulimit -Hn`:
|
|
||||||
|
|
||||||
```bash
|
|
||||||
$ ulimit -Hn
|
|
||||||
1048576
|
|
||||||
|
|
||||||
$ ulimit -Sn
|
|
||||||
1024
|
|
||||||
```
|
|
||||||
|
|
||||||
Increase the soft limit before starting Dendrite:
|
|
||||||
|
|
||||||
```bash
|
|
||||||
ulimit -Sn 65535
|
|
||||||
```
|
|
||||||
|
|
||||||
The log line at startup should no longer appear if the limit is sufficient.
|
|
||||||
|
|
||||||
If you are running under a systemd service, you can instead add `LimitNOFILE=65535` option
|
|
||||||
to the `[Service]` section of your service unit file.
|
|
||||||
|
|
||||||
## DNS caching
|
|
||||||
|
|
||||||
Dendrite has a built-in DNS cache which significantly reduces the load that Dendrite will
|
|
||||||
place on your DNS resolver. This may also speed up outbound federation.
|
|
||||||
|
|
||||||
Consider enabling the DNS cache by modifying the `global` section of your configuration file:
|
|
||||||
|
|
||||||
```yaml
|
|
||||||
dns_cache:
|
|
||||||
enabled: true
|
|
||||||
cache_size: 4096
|
|
||||||
cache_lifetime: 600s
|
|
||||||
```
|
|
||||||
|
|
||||||
## Time synchronisation
|
|
||||||
|
|
||||||
Matrix relies heavily on TLS which requires the system time to be correct. If the clock
|
|
||||||
drifts then you may find that federation no works reliably (or at all) and clients may
|
|
||||||
struggle to connect to your Dendrite server.
|
|
||||||
|
|
||||||
Ensure that the time is synchronised on your system by enabling NTP sync.
