Poor performance

Hi all,

We are having performance problems during the day. glpi becomes slow for a few minutes and then works fine. It doesn't seem like resource or scheduled task problems. How can I check what is happening?

Thanks,
Regards.

Re: Poor performance

How are the automatic actions configured to run (GLPI or CLI/Cron mode)?
What plugins do you have enabled?
Which version of GLPI?

Is there any other information you can give about the issues?

Hi cconard96,

Automatic actions execution mode: Mixed, I only changed GLPI to CLI createinquest and queuednotification (executed each 20 mins)

Plugins enabled: Tags 2.12.1, Additional field 1.21.11, Behaviours 2.7.3, Formcreator 2.13.9, More Satisfaction 1.6.2 and Trademark 1.4.1

GLPI 10.0.14

I have enable debug mode but I dont know how use it. Doesn't seem a database query issue because when hang I can go to any menu during 1 or 2 minutes (slow performance for all users), then work fine.

Thanks,
Regards.

Re: Poor performance

Did you increase the Memory Size for the Zend OPCache ? ( I know I increased mine to 256 MB [overkill I know but I'd rather have that than not have enough])

Yes, It was first I did. Currently is 56.48 MB / 256 MB

Re: Poor performance

If GLPI is slow for everyone at the same time, then it is probably a resource utilization issue with the server that GLPI is running on rather than something with GLPI itself.

Re: Poor performance

Thanks for your response. I don't think it's a resource problem. I've been monitoring them and don't see any significant increase in memory or CPU usage. Glpi is running on an exclusive virtual machine with 8 vcpus and 16 gb of ram... I don't know how to troubleshoot it.

Re: Poor performance

Hi All,

We continue with performance issues...  Could having the browser open in debug mode interfere with performance?

Thanks,
Regards.

Re: Poor performance

Debug mode mainly just affects your own performance. A lot of things don't use a cache when in debug mode so it is possible that if enough people are in debug mode and doing things that require regenerating data that would usually be cached in their browser or session it could affect the server performance. This would really depend on your GLPI's complexity and how many people are in debug mode accessing things at the same time.

Re: Poor performance

One of my test was set OPcache to 1GB, now in performace tab is marked with warning because only a 5% is used... I understand that low opcache does not mean low performance, no?

Thanks,
Regards.

Re: Poor performance

Opcache is used to cache the compiled bytecode of the PHP files to avoid having to parse the scripts for every request. You don't need a lot of space for this. My development installation of GLPI 11 only takes about 75 MiB in Opcache. If you have extra space available for opcache, it shouldn't affect performance; Only if you have too little space.

Re: Poor performance

Can you use something like Zabbix to monitor performance? Maybe it could help
