First you should have separate drive for squid cache, then about filesystem (although some ppl blame ext2, some blame reisersfs), storage type, enough of free space (full filesystems use to have noticeable slower performance) and enough of memory for cache. > Is there really a noticeable difference in seek/total I/O performance ? There are expectations that at the begin of disk there should be lower seek performance, but better performance for sequential reads, and in the middle of disk there should be higher seek performance wit lower performance for sequential reads. However ad I use two whole drives on all of my servers, I haven't checked this. -- Matus UHLAR - fantomas, uhlar@xxxxxxxxxxx ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
