Re: Startup speed: Still too many stats?
I see this growth on FAT volumes and cd roms, but not on NTFS
volumes:
NTFS drive:
8 stats in 7 ms, 897 us per call
398 stats in 318 ms, 799 us per call
2481 stats in 2041 ms, 822 us per call
FAT drive:
9 stats in 8 ms, 922 us per call
54 stats in 43 ms, 802 us per call
679 stats in 678 ms, 999 us per call
1291 stats in 1595 ms, 1235 us per call
CD rom:
42 stats in 132 ms, 3154 us per call
789 stats in 5917 ms, 7500 us per call
Just as a side note. Wow, microsoft "operating systems" really blow.
IRIX 6.3 (on an O2 [R5000, 180MHz]):
:; /tmp/stat_time
2334 stats in 1694373 usecs
725 usecs per call
:; /tmp/stat_time
2334 stats in 371815 usecs
159 usecs per call
NetBSD 1.3 (on a PPro 200):
:; /tmp/stat_time
299 stats in 18712 usecs
62 usecs per call
:; /tmp/stat_time
299 stats in 6898 usecs
23 usecs per call
(note that the second invocation has the meta-data already in the buffer cache)
