Hello.

Actually I ran:

    time ./ls.exe -lR c:/temp/distmake > /dev/null

I tested on Windows '98 SE.

ls from Fileutils 4.1 built against v2_03_1:

Uncached:
    real    1m48.700s
    user    3m37.473s
    sys     0m0.000s

Cached:
    real    0m50.700s
    user    1m41.429s
    sys     0m0.000s

ls from Fileutils 4.1 built against HEAD:

Uncached:
    real    1m45.570s
    user    3m31.209s
    sys     0m0.000s

Cached:
    real    0m59.650s
    user    1m59.341s
    sys     0m0.000s

There's not much difference between v2_03_1 and HEAD. A difference of a few
seconds is probably due to whatever else was going on. (I was listening to
MP3's at the time of testing.)

Could someone else test on Windows 2000 or XP please? You can find my test
results and executables here:

I can post the gmon.out files from my runs there too, if people are
interested.

Bye, Rich =]
