The question wasn't if 2% is significant, but if the measurement was statistically significant. Sure, it was measured. But was it a real measurement, or a stopwatch error. In truth, Novell's Perform3 is not the best of tests.... I've seen a number of nets performing at 110 to 120% of their available bandwidth.... > A fundamental design element for a server OS (as opposed to a > desktop OS) is to always assume that *every* cpu cycle is valuable. Okies... if you say so... still, 2% change can be caused by a driver change. And the results are only valid on the OS where they were tested. With the patches in place. etc, etc, etc. Mike ====================================================================== Mike Avery MAvery@mail.otherwhen.com (409)-842-2942 (work) ICQ: 16241692 * Spam is for lusers who can't get business any other way * A Randomly Selected Thought For The Day: Confession is good for the soul, but bad for your career.
