hi michiel,
thanks a lot for your answer.
so, i did the comparison. everything excepting sending an email is pretty fast (about 2-5s für 10MB). sending an email with 10MB as an attachment takes about 3 minutes. at this point you will say, that there is a problem with the mailserver... but i am not sure. if i really had a problem with the mail server, then i would experiencing exactly the same behaviour with unsing an email client... but the email client sends also pretty fast and so i would say that this is not the bottleneck. what about perl? if i understand otrs code well, there is a transformation into base64 and during the 3 minutes trying to send the email, i recognize a very high load of the server cpu (100% on one core). don't you think that there is another problem that is maybe placed into the transformation into base64 or maybe something directly with perl...
thanks again for your help.
regards,
patrick.

Hi Patrick,
An obvious question would be: is the mail server the component here
causing the trouble?
If adding the attachment to a note takes as much time as adding it to
an email, it is caused by OTRS. Otherwise, your mail server is the
bottleneck here.
((enjoy))

hi,
first my setup:
otrs 2.4.7
win 2003
mssql 2008
perl 5.10
apache 2.2.10
mod_perl 2.0.4/dev
we are experiencing that sending emails with large attachments (> 5MB) through otrs takes very long. i am talking about 2 minutes or even more... 4 minutes when the attachment ist about 10MB. i tried to change the storage placement from DB to FS, but it didn’t change anything. unfortunately i don’t get any more specific informations in the log files.
does anyone have some similar issues or maybe someone of you guys has a solution to this problem ?
thanks for your help.
regards,
patrick.
