Hello, I have a base with something close to 6k of attendants, when I need to add attributes of owner and note in detereminado group (client) it stays for hours updating. The bank is OK after tuning (I set it with MySQLTuner-perl and more

), now the problem seems to be in Apache, it consumes almost 100% of the CPU.
otrs version= 5.0.14
mysql version= 5.5.53

OTRS 5 + MySQL + Debian Linux.
