Performance issue when creating/modifying bug

[gbe]

Hello,

We''ve just set up a gmail account (POP3) and tested the emailreporting. Bug are correctly created but we are facing performance problem.
Indeed, when we trigger the collection of email (/mantis/plugins/EmailReporting/scripts/bug_report_mail.php) it last more than 20 seconds and block any other usage of mantisBT...

This issue is only relevant when there is at least one email to collect on our gmail account.

Any idea to fix this problem ?

How do you execute the script? through the command line or a web browser?

[gbe]

I click on the link available on the configuration page (/mantis/plugins/EmailReporting/scripts/bug_report_mail.php)

[SL-Gundam]

The only thing i know is that PHP on Windows in threaded SAPI mode seems to have an issue sometimes where the scripts will finish in order even if the latter script should have finished sooner. I don't see any way in which EmailReporting itself could cause this

The reason the execution of EmailReporting's script thats longer then normal might be the connection with the mail server which might be slow

[gbe]

It does not come from the connection to the server as when here is n email to analyse, the job is really fast.
It is only long when there is at least one email to deal with (more than 30 seconds for one email...)

[SL-Gundam]

So far there have not been any performance issues with EmailReporting. So if i can't reproduce it, i cannot fix it.

So that leaves 2 options:
- you debug EmailReporting and find the problem and post it here so that i can check it out further
- I debug EmailReporting on your server and find the problem.

[gbe]

Ok
We try to debug Email Reporting and I let you know.
Thanks

[gbe]

We found that the performance issue is in the Mantisbt standard and is not relevant to EmailReporting.
Thanks for your help !

[SL-Gundam]

Ok thanks for checking.
