Version 9.4.1.1 slow performance

Hi, anyone noted that latest version are very slow compared the version 9.3?

Looking for the problem I saw that just to  enter in a ticket left 5 seconds to render common.tabs.php...

Does anybody know how to solve this slow performance?

Thanks

Re: Version 9.4.1.1 slow performance

in 9.4 you have more javascript than 9.3


CentOS 6.5 - CentOS 7.x
PHP 5.6 - PHP 7.x - MySQL 5.6  - MariaDB 10.2 + APC + oOPcache
GLPI from 0.72 to dev version

Re: Version 9.4.1.1 slow performance

Yes, i have performance issue on 9.4.1.1 too.

It appears that apache2 process use 100% of Cpu sometimes. At this time, i don't know what is the cause of this issue. I'm trying to search on log (apache & Glpi).

Do you use order plugin ? I see lot of Php errors on this plugins...

In my case,  have also change crontask scheduling for update of OCs Inventory synchronization and LDAP users. (1 time a day instead of each hour...). it's better, but they are another issue.

All my cron tasks are CLI, so it is not did by GLPI webfront.

I don't use order plugin, but I use a lot of others, I will find where is the problem.

Re: Version 9.4.1.1 slow performance

Hi

I have the same issue on Ubuntu 16.
Very slow since 9.4.1.1 upgrade.
Many issues with LDAP synchronisation. I think I will rollback to V9.3

Re: Version 9.4.1.1 slow performance

@daniele.phobos.

Do you have opcache and apcu enabled for your instance ? (mostly opcache)
By the way, you should consider upgrade php to version 7.x (7.3 if you can), performance between php5.6 (end of life) and php 7.2 are x2.

With the patch we talked this afternoon, on my laptop i currently have response time below 1s.
6.5s is still very slow

Re: Version 9.4.1.1 slow performance

yes..512Mb of opcache and apcu too (barely used apcu)

i know about php..i've to use multiple version, because a lot of 5.6 php plugin for our wp intranet, i will implement this week if i can.


edit: i forgot..i've increased opcache and temp table memory size in mysql too .now loading time is about 1.75 seconds

i noticed that 9.4 use really a lot more of sql query than 9.3

orthagh I hope this is good, to be honest I am not a programmer and I do not understand how to apply the solution proposed in the log, you could be so kind to guide me a little better, thank you very much

Re: Version 9.4.1.1 slow performance

If you want, you can simply get the nightly version here : https://forge.glpi-project.org/tarballs … xes.tar.gz
Or wait for 9.4.2.

Is the wait for 9.4.2 going to be long, Orthagh?

@ortagh This week I upgraded to version 9.4.2 and improved noticeably. the difference in the opening of tickets and in the drop-down lists is considerable.
Thank you very much everyone for your interest and for the answers allowed
