I wonder if you could help. I am not sure when the issue started, most likely when I upgraded osTicket to 1.9.4 a couple of months ago or a bit later. I am experiencing big performance issue whenever I submit anything from the agent panel like upgrading a ticket description etc. It sometimes takes 30 seconds up to 2/3 minutes to save the form. My database is really small (600+ tickets). The server is not busy with other applications whatsoever -- when I look at the performance graph it shows disk activity next to nothing (0-3%). But when I try to save anything -- it goes really mad and quickly jumps up to 90-100% of the volume/iSCSI activity (see the attached picture) and the whole server becomes unusable... :(I did a disk S.M.A.R.T test, mysqlcheck, defragmentation etc etc -- no help at all! Recently I upgraded to 1.9.7 -- same issue.My machine is Synology DiskStation DS214Play.Please advise what else I can check/optimize. Any help will be greatly appreciated.
