Hi,
I have read the GUIDE.pdf file about Performance and Server Mode but I did
not understand how can I make a fast upgrade to server mode, I have some
doubts also because it is a production server.
Thanks in advance.

Hi, I use Qpopper 4.0.9 on Fedora Core 5 and hardware resource are:
CPU: Intel Xeon 3.00 GHz
Memory: 3 GB RAM
Disk: two hard disk from 72.8 GB/10.000 RPM/WIDE ULTRA320 SCSI in RAID 1
I have about 700 users and from a few days I have a dramatic perfomace
problem because in some hours the queue increase in excess mode and I
have more 800 mails in spool directory !I use qpopper in standalone mode
and I use -s -R options:
[EMAIL PROTECTED] ~]# ps -ax|grep popper
19147 ? S 0:00 /usr/local/sbin/popper -s -R
..if popper service is stopped the queue are emptied in a few minutes.
I have read the documentation about 'Perfomance' but I haven't solution
for my problem, What can I do to solve my problem ?
Thanks in advance.
When you say you are experiencing "queue increase" you mean that incoming
mail builds up and is not delivered?
Is your system CPU-limited, memory-limited, or I/O-limited? That is, if
you use any kind of performance monitor, even just 'top', do you see high
load average and no idle CPU? Or, are you seeing excessive pageouts?
Also, have you tried enabling server mode? As long as your users don't
access their mail using any sort of local program, it should be OK. You
can try also setting fast-update. See the "Performance" and "Server Mode"
text in the GUIDE.pdf file.
