I have osTicket running on an almost-bare linux server (Xubuntu linux, typically running w/o the GUI, on a 2.5 GHz Celeron PC w/528 MB of RAM). While the page loads very quickly, it's very slow to submit issues or changes to tickets. Since this slowdown began after I installed sendmail, + can only presume that it has to do w/the sendmail configuration.
Is there a recommended sendmail.cf to optimize the speed of osTicket? Or, is the reason for the speed problem simply b/c Perl + PHP scripts aren't generally known as screamers?
Any help would be much appreciated.
