Where as that Database is going to get 2 hits, Moin is getting how many? Even on Moin caching operations has to Traverse many Directories where as simple Index Querie results in 2 hits. Hit the index + file = 2 hits. Take a look at the Moin Data directory and tell me how many directories you travers to get to that one specific wiki article. Yea, I once at a time had an install of Moin and dumpped it when I found out how it stored my data and the markup it put in it. DB thrashing is no problem. Load up those tables in RAM and evaluate the queries that is causing it. Going from TSQL to SPROCS to VIEWS and Triggers can solve many of those problems in it self. I can understand people have different opinions but I've had the real world problem dealing with it. JohnStanley
