128 mb is too much mark. if you try to look at cachemgr.cgi memory utilization and try
to compute with an average of
13kb object size. for every 1 gb of disk cache, you will consume more or less at
around 12 mb of ram. for a safe
figure and ideal ratio, for every 1 gb of disk cache, 16mb of ram you will be going to
allocate it for squid only. but
of course another extra ram for your system's disk buffering and for other processes.

basis for this is to increase request per second throughput across multiple disk.

if you have only one disk, dont partition it. *but* dont allocate the whole disk for
disk cache, leave extra disk
space for filesystem fragmentation activity.
fooler.
