Hi, At TPC5 I'll be doing a talk on "Real World Performance Tuning", http://conferences.oreillynet.com/cs/os2001/view/e_sess/1260 I'll be talking about what things to work on to make your system scale better by not 10% or 20%, but hundreds of percent. That sort of thing. If you have a cool story about how you made your system a fraction of the memory it used to, or how it could serve thousands of requests per second instead of hundreds, then please send them to [EMAIL PROTECTED] :-) - ask -- ask bjoern hansen, http://ask.netcetera.dk/ !try; do();
