Our biggest issue is still the performance, OTRS5 used to hum along nicely on our hardware. OTR6 is pretty unusable at times it is SO SLOW. I have had no success in actually identifying what is slow. I did find an article regarding a potential missing index on a table and added it but it didn’t make much difference. If anyone else has managed to fix the issue or you didnt see a slow down in performance after the upgrade, I’d love to know what is different between our environments. We had OTRS5 on Fedora 24 but have OTRS6 on Centos7 with 4.13 kernel and Apache 2.4.6-67, perl 5.13. PosgreSQL 9.6.6 is on another server. Any pointers would be appreciated. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Glen Eustace, GodZone Internet Services, a division of AGRE Enterprises Ltd., P.O.
