The numbers reported can't be higher than the actual time slept, regardless of clock granularity. Okay, if you round up sometimes, it can be off by a little, but the amount we're off is actually huge. In other words, what Guo reported in #5 is likely just that, approximation error which can easily by fixed with a tiny bit of math to give some amount of fudge in the positive direction. However, the original numbers that Wendy reported aren't multiple reads, there are exactly 2 reads, and the application completed in exactly 0m10.002s. I don't believe this explanation for the 1.14 real 0m10.002s user 0m0.000s sys 0m0.002s BEFORE = 1281484 AFTER = 1292928 DELTA = 11444 1.14</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
