RAID1 here behaves as one disk and that means you should use single cache_dir on it. > Currently in production we have two squid servers - pentium III's 1.5GHZ's > raid 5 (3 76GB Drives) with 4 cache_dirs...Only about a 1-2 second delay if you set up no raid or raid1 here (and use one cache_dir per raid), you'd probably notice berformance advantage, even with hardware raid, and especially with software raid. maybe you won't need new machines at all :-) > before a web page is brought up This is with cache_peer parents that are new > McAfee webshield web scanners, and 2 new DNS servers that receive about 20 > queries/sec.
