That is an interesting point. It is amazing how many directory type things get slammed, but the problem is really latency...such as a slow DNS lookup. I wonder how much quicker an easy_install would be will local DNS lookups,package names, etc. I had a problem with a LDAP server I setup that was really tricky to figure out until I wrote some scripts that ran continuously getting stats, and I realized that a DNS server would hang occasionally and it would grind everything to a halt. People kept telling me they would have an occasional 'ls -l' that would hang for 20 seconds. Caching DNS servers fixed it. Jim
