I have applied this patch to the 1.6.2 and the load-average is now OK.

Just wondering, how much above (or below) the qmail-pop3d ? And what about the 700MB unused free ram, cant you turn this into nfs/disk-caching buffers somehow ?

There are pretty equal :

qmail-pop3d : IRIX64 vercors 6.5 IP27 load averages: 0.70 0.78 0.79 15:26:13 82 processes: 81 sleeping, 1 running 2 CPUs: 77.3% idle, 7.9% usr, 14.5% ker, 0.0% wait, 0.0% xbrk, 0.2% intr Memory: 1152M max, 868M avail, 725M free, 1024M swap, 1024M free swap

courier-pop3d: IRIX64 maupassant 6.5 IP27 load averages: 0.80 0.89 0.80 15:27:42 87 processes: 86 sleeping, 1 running 2 CPUs: 80.5% idle, 6.2% usr, 12.6% ker, 0.0% wait, 0.0% xbrk, 0.7% intr Memory: 1280M max, 807M avail, 646M free, 1024M swap, 1024M free swap

For memory, i don't spent time to tune theses servers that i'm replacing by linux server (yeap, maintenance price are reaaaaallllyyyyy expensive for these old SGI server) :)

Now, i don't understand why this is not the default method. To be RFC Compliant is ok, to be efficient is better i think.

The former is a requirement, at least if you use samware ;)

ok :))

Because having a problem with 100 connection with a dual processor server and two network filer F760 as storage system is not acceptable.

The problem has been already mentioned on this list, pop3d cant be used for anything with more than a few mailboxes and Sam recommends using imapd in such cases. Maybe this makes it into a configure-time option some day, but non-rfc-conformant hacks usually take some time.

Well. But i don't want to give imap access to our customer.

Do you know if there is the same problem with imap server ?

No. imapd uses stat() to get the filesize. You will have other problems because most clients open up too many concurrent connections, stay connected for some time and will never delete old mail. Set maxperip to 6..8, maxdaemons to >1024 and watch your network-buffers.

We are already using imap server but internally to use with our webmail. I have no problem today with that, but we have a few number of connection (~40-80).

Tks.

Roland
