I have a file testing program that creates, writes and indexes a file on the server from the Windows client. On xpp sp1 the program takes 7 sec to write file and 8 sec to read the indexed file. After telling the Firewall to go away I can get the following numbers from xpp sp2; 29..30..45 (tested multiple times) sec to write the file and 7..8 sec to read the file. Any ideas on why the 'best' performance of sp2 is 4+ times worse than Windows XP Pro SP1? I really don't want to ship a system with this type of performance degradation. As a side note; initally the file write performance was in the 120 sec range, 17 times longer!! Why hasn't this been reported and/or what is strange about my systems? ps. the Client hardware AMD1800+.... is identical on the SP1 and SP2 machines. Any help on this would be very appreciated. John.
