Sadly, when I go to the second set of tests (20,000 files and 50,000 transactions), my performance goes into the crapper. I know that softupdates trades memory for speed, and I guess this PPro 200 w/ 128MB RAM just doesn't have enough memory to keep up. For this stage, I now get: Transactions per second: 33 KBytes Read per second: 79.66 KBytes Written per second: 144.31 The third stage of testing (20,000 files and 100,000 transactions is now underway. -- These are my opinions -- not to be taken as official Skynet policy ____________________________________________________________________ |o| Brad Knowles, <blk@skynet.be> Belgacom Skynet NV/SA |o| |o| Systems Architect, News & FTP Admin Rue Col.
