Hi,
That version of Redmine seems quite old so if possible maybe try and update it to the latest version.

Thanks

Is there any other way besides upgrading the new version? Because there are plug-ins that do not support the new version, and many people are using the system, it is not convenient to update.

The most feared is that the problem is not solved after the update.

Is there any other way to optimize or check the problem?

you should use a more recent Redmine version in terms of performance and security. Redmine 3.4.6 is no longer supported. All plugins you have installed should work (or with a little effort), but they may need an upgrade aswell.

How can I find out where the problem is?
1/ I would recommend you to track slow DB queries. Find out why they're slow with EXPLAIN https://www.exoscale.com/syslog/explaining-mysql-queries/
2/ try it without plugins
3/ use a profiler like https://github.com/MiniProfiler/rack-mini-profiler (advanced)
4/ it could be something completely different, it's hard to guess why is Redmine slow on your own server without actually knowing anything specific.

Or how to clear unwanted junk files?

==============================================
I'm not sure, I guess it may generate too many log files for a long time operation.

Or is there any way to check which log files are there? Find out the reason for slow writing from it?

Because it is very fast to do query or read project issues, only the modification and creation speed is very slow.

I'm not sure, I guess it may produce too many log files if you use [remdine] for a long time.

Or are there any log files that can be checked to find the reason for the slow writing?

Hi there,
I found the main reason.
