Thanks Greg and Matthew. We're a small to medium sized ISP supporting about 4000 users and processing approx 85,000 to 100,000 pieces of mail per day. We generally use very little of our swap, normally around 100MB or so. However, the problem is that during our peak times or if someone is trying to check their POP mail and they've got a very large file (I'm trying to weed them all out and educate them on this issue, we aren't using quotas and that's a *whole* other story) the machine really stresses trying to handle it all. Does this sound like something that the RAM will fix, or am I totally on the wrong road? Rob Wright poncacity.net robwright@poncacity.net At 13:14 2/12/01 -0800, you wrote:

Oh yeah, if you're only running a mail server are you sure you need the 1GB? Have you checked swap usage? Is it supporting a really large company or processing large lists? Sendmail/POP3 aren't like bloaty Exchange or Notes. The RAM may be more useful elsewhere.

If you do not have SCSI disks, it would be wiser to buy a faster hard drive then more RAM, imho.

hi all, ywah, i forgot to mention this too in my last mail. scsi gives you much better performance as ide...... for ide the cpu has to handle the whole i/o whereas scis does it itself. (scsi controllers are "intelligent" whereas ide controllers are "dumb") greets, chris On Montag, 12. Februar 2001 22:31, Jonathan Wilson wrote:

hi rob, were running an email server which handles approx. 40.000 mails/day its running on an old pentium 233 machine with 128 MB of ram. with sendmail and inetd it all draws down, i have switched to qmail and xinetd. this has speeded up our machine alot. configuring qmail can be a hazzle, but its worth to do so. if you plan to swith over to xinetd take care : i had the problem with ipv6 beeing translated to ipv4 which xinetd and qmail doesnt like, as they dont know about it by default. so you have to disable ipv6 unless you really need it (then you have to recompile the others...) but despite this, it works well ..... greets, chris On Montag, 12.

As Jonathan mentions in a later message it sounds more like an I/O problem. I would put enough RAM in to avoid swapping and consider ways to get better I/O. Greg
