Re: [squid-users] Recommended RAM

2000 reqs/sec? So you're supporting a 155Mbps link?

A single Squid box will not do 2000reqs/sec no matter what you do. Very
few web caches will, and certainly not from 2 IDE disks (at the
cacheoff, you'll see boxes with 16 SCSI Ultra 160 disks doing about that
rate--and they aren't running Squid).

I'll guess you mean 2000/min?

If so, that's not too hard at all even without an async i/o compile.
But you don't have enough RAM for 70GB of cache_dir space. 1GB of RAM
/might/ make it. I would actually recommend you drop the size of your
cache_dirs some, and raise the RAM some as well.
