I've heard that COS5 is more of a pig, and I'm not really sure how/why that is. I can't believe it's all in the kernel (COS4 is 2.6.9). Keep in mind that Linux will use what you give it, for caching and such. I usually look at swap/paging to tell if more RAM is needed or not. I'm no expert with performance tuning though. -- -Eric 'shubes' - QmailToaster hosted by: VR Hosted http://www.vr.org - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: [qmailtoaster] Server Suggestions
Hmmm.. maybe I don't need a new server. But I want one! My current server specs are 2 x 800mhz P3, 2gb RAM, 4x18gb RAID5 scsi2. The I/O throughput on the RAID isn't the fastest. Backups take a long time, because we use IMAP and use the server for mail storage. Backup Start Time: Thu-03/27/[EMAIL PROTECTED]:30:08-EDT Backup End Time: Thu-03/27/[EMAIL PROTECTED]:54:56-EDT I have 2 more DL 380's with similar specs. One we filled with 4 x 500gb SATA drives, RAID5. The other has 2 x 500gb IDE drives, RAID0 and 4 DLT 7000 drives connected. 4 years ago, when I started here, they were running Win NT 4.0 and having problems. I installed redhat, and the problems went away. Now I feel like the Maytag repair man in the commercials.

RE: [qmailtoaster] Server Suggestions
I would suggest: http://outlet.us.dell.com/ Pick up a refurbished Dell 1950. They have dual hot-swappable power supplies and hot-swappable RAID1 (make sure you get one with a RAID controller) drives. If happen to find dual-CPUs, or even quad-core CPUs in your price range, don't be afraid to install VMware Server and run your toaster as a VM. I have found that RAM and Disk I/O are the highest point of contention on my toaster, which hosts thousands of addresses.

I enjoy reprovisioning older hardware. What you have for 20 users really should be adequate. I've run a small businesses on PII 1x266. As Jake said though, ram is key. 512M runs nicely. Much more than that is overkill for a small standalone toaster. Also, I like using software raid1 with 2 drives (KISS). -- -Eric 'shubes' - QmailToaster hosted by: VR Hosted http://www.vr.org - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
