Hey Mario, you can change the standard setting at these keys in the sysconfig: PreferencesGroups###TicketOverviewSmallPageShown PreferencesGroups###TicketOverviewPreviewPageShown PreferencesGroups###TicketOverviewMediumPageShown PreferencesGroups###NotificationViewSmallPageShown PreferencesGroups###DynamicFieldsOverviewPageShown PreferencesGroups###CommunicationLogPageShown Do you have the performance problems with the search or with the queue? If I set this value to 250 tickets per site, I'll get 15 seconds for the "all queue view" and 30 seconds for the search. I bet the operations on the index grow exponential. A possible explanation for your ticket <-> article discrepancy: you could check if merged tickets have an article, if I remember that correctly, the just get the link.

Hello, i have about 63.000 Articles and 94.000 Tickets (huh? thats possible?) After Upgrading from OTRS 4 to 6 Tickets with more than 200 Articles are very slow. About 30Secs to load. If i set the view to display only the last/one Article it just needs 6 seconds. I read: https://doc.otrs.com/doc/manual/admin/5.0/en/html/performance-tuning.html - i am already using ArticleStorageFS - i am using tmpfs now for /opt/otrs/var/tmp - i archived 22.000 Tickets But the Tickets with many articles are still slow. I have LocalAvatar-6.0.5.opm installed, which prevents slow connections to the outside. I doubbled the RAM (now 24GB) and CPUs (now 12) after Upgrade and it runs on SSDs. The DB is about 5GB (innodb) I cant seem to find a bottleneck on the hardware. I kind of have the feeling its some sort of timeout or call to the outside. What do you think? The search speed is fine. Could a change the ArgentTicketZoom to just Show the last 10 Articles by Default? Thanks, Mario
