Zammad Very Slow

  • Used Zammad version: zammad-2.9.0
  • Used Zammad installation source: RPM
  • Operating system: Centos7

Expected behavior:
Fast response .

Actual behavior:
The zammad system is very slow 4 weeks before and employees can’t work as fast as possible.

I have executed the command “htop” in the Zammad host and seems like these 2 process are using a lot of CPU:

Please any suggestions?

Please provide us info:

zammad run rails r ‘p Delayed::Job.count’
zammad run rails r ‘p Delayed::Job.first’
zammad run rails r ‘p Delayed::Job.last’

Hello @atimias

zammad run rails r ‘p Delayed::Job.count’
0
zammad run rails r ‘p Delayed::Job.first’
nil
zammad run rails r ‘p Delayed::Job.last’

Are logs showing anything interesting?

Beside the failing mail login on IMAP, I’d be interested what your hardware specifications are and how many agents you have concurrent.

Hello @MrGeneration

Hardware information: 2x4 CPU Cores and 16GB RAM.

And sorry what do you mean about “agents you have concurrent.”, and how can i check them?

Thank you in advance.

I don’t think we have a tool that shows how many agents are online at a time.
What I mean with concurrent agents is the number of agents being online and workin in zammad at the same time.

CPU doesn’t look to bad (I mean if you’re not working with IDE drives :stuck_out_tongue: )

Please, think to add one in the future zammad versions :laughing:

For the agents, 18 are working in zammad at the same time.

by the way, i have found this command her High Latency , Timeouts, tickets twice

zammad config:set WEB_CONCURRENCY=4
systemctl restart zammad

Is it useful in my case ?

For me this helped:

zammad config:set WEB_CONCURRENCY=4
systemctl restart zammad

After the restart the Delay in our System was away. In first step i set 2 Server processes. If needed i will try a higher Number :wink:
