Hi all,
I have a server which has about 50.000 e-mail accounts. POP3 concurrency is
set to 150 and timeout to 90 seconds. A couple of days ago, my users
started to feel a huge delay in getting their messages via POP and
sometimes, they even cannot connect. I checked the number of simultaneous
number of connections and is not close to 150. Of course, concurrency
increased a little bit ( around 100 ) in the past few days, but it didn't
reach the limit yet.
I think my machine is on its knees right now :((, but I cannot afford to
have a better hardware at this moment. What can I do to improve
performance ? ( I mean software performance... ). The migrating to vpopmail
would help ? What about mysql to authenticate users ?
Thanks

P.S. I'm using qmail+vmailmgr, so I have thousands of passwd.cdb files...
