Ya, stock redhat enterprise and centos are coming that way now.

>16GB

hmmm - I was under the impression it could recognize up to 64gig of ram?

Ya JAB, I mean the server is only using about half the memory right now to run the server. We'll see how that holds next week when server load doubles and we flip on mod_deflate.

Typical memory usage so far:

total.......used.......free.....shared....buffers.....cached
8300496....2910580....5389916..........0.....379160....1956632
-/+.buffers/cache:.....574788....7725708
Swap:......5156856........116....5156740



I have a programming project that is going to need about 2gig in a ram disk for a ultra fast random access db. Linux has a killer disk cache system by default. It is almost always as fast a ram disk. The one exception where a ram disk will beat a disk cache system is on a web server system when dealing with thousands upon tens of thousands of files and/or lots of disk writes inner-spaced with reads. (going to toy with putting the entire board into a ram disk and see what happens - I think it will be radically faster - and a fun project)

Other than that, I think I got all the box we could take advantage of here.

>The average Apache process running on the server will use in the order of 10MB.

Ya, most threads appear to run about 4-5meg. The largest 5% of threads can pull 15-20meg on replies. Mod and Admin actions (like move thread to new forum), can pull 30-50meg). We will be addressing that top usage problem shortly (eg: fixing the dreaded 'forum x needs to be reindexed issue).

> Only until you've done it.

Maybe it is just me then Wheel. Remember, I've been doing this for a few years. Having "my box" on someone elses property, feels wrong. I've always been a 'buy - don't lease' kinda guy. It's moot anyway until I find a killer location for an office with lower priced inbound internet. I hear there is space next to Googles Austin office on Mopac (not kidding).
