Hi Nils, It would be too much work to rewrite it to PHP. But that's only an observation from myself, all tests I did to see where was the problem of this regular slow impression in OTRS leads me to the code, after eliminating Web Server performance/tuning, DB backend ... OK Perl itself (as a language) is not the culpit but maybe the way it is coded here can be improved ? Or maybe is it mod_perl ?
I tried a few weeks ago to rewrite some simple parts of the code (the overview listing of CustomerUsers trough Admin Panel (AdminCustomerUser.pm)) in PHP and with the same server/db backend, i was having some response time far better (almost 2x faster) ... OK, I didn't re-coded all parts of OTRS internal systems functions but only a little part of the code and it shows me that there is some things to improve about performance ... I don't know enough Perl to discuss about pass by reference / pass by value but it can be a good thing on which it may be needed to take some time :) BR, Laurent Minost Le vendredi 31 août 2007 à 14:31 +0200, Nils Breunese (Lemonbit) a écrit : > Laurent Minost wrote: > > > DB backend were never the problem in all my cases and always though > > that Perl is the culpit. > > PHP/MySQL seems to me solutions easily faster than Perl one for Web > > applications... > > I really doubt that the language is the problem.
