Actually, it's a 1.1ghz Celeron, which from past experience, has been more than enough to handle the load. others? > > > > Memory usage looks low, usally at 20%. never seems to get abouve > > 25%, So I'm > > pretty darn sure it's not a memory issue.

What's running slow? No. Please read what I wrote. Memory usage is low. Paging is low. **CPU** usage gets pegged to 100%. There is a difference in memory, disc usage, and CPU cycles. Yes, Memory usage CAN be low and disc usage CAN be low and the CPU can still be over worked. > How fast are the page loads? Page loads "seem" normal UNTIL the CPU gets pegged than it slows to a crawl. Page load time isn't really a good diagnostic either, because the images are being served from a separate server, which is as fast as it's ever been. > big are the mailboxes? Most, rather small. Mine, really big and many of them. >How many mailboxes per user? 5-10 maybe, at maximum. I'm the exception, as I've had the same address for 8+ years and have bounces and whatnot forwarded to me. I've also made big use of the automatic mailbox creation feature when signing up on websites, which creates a new mailbox each time i put an email address on a website. Cleaned off 100 mailboxes and still have plenty left to remove. > And EIDE Hard Drive is > way to darn slow for high disk I/O for IMAP mailboxes that are extremely > large. Yes. This is understood. The real question to be solved is why an upgrade from 7 to 8 would cause IMAP4 to peg the CPU. > It's been said on here before and has been shown that upgrades can > make underlying problems more noticeable than before. That's what we're here to figgure out, is it not?
