Wow! A rave from the grave :)

This thread relates to an very old version of Time::HiRes. Later versions use a different system API to allow much higher resolution. For further reading see thread at Perl -de1 weirdness. and particularly Re^4: Perl -de1 weirdness..

The resolution under windows is now comparable at around the 7 microsecond mark (on my machine. It will vary somewhat with the speed of your cpu). Certainly faster than a Perl script can report it.

Though the weirdness with Time::HiRes when running under the debugger persists into 5.8.6: 

C:\perl5.8.6\bin>.\perl -MTime::HiRes=time -le"print time() for 1 .. 1
+0;"
