Re: technical comparison

[Andresen,Jason R.]

I just finished the FreeBSD test with

vfs.vmiodirenable=1 (it was 0 before)

60000 simlultanious files, 10000 transactions, FreeBSD
4.0-Release+Softupdates with write cacheing disabled.  Results are pretty
much unchanged.  Do you have to enable vmiodirenable at boot time for it
to take affect?

Time:
        1286 seconds total
        505 seconds of transactions (19 per second)

Files:
        65065 created (50 per second)
                Creation alone: 60000 files (85 per second)
                Mixed with transactions: 5065 files (10 per second)
        5078 read (10 per second)
        4921 appended (9 per second)
        65065 deleted (50 per second)
                Deletion alone: 60130 files (761 per second)
                Mixed with transactions: 4935 files (9 per second)

Data:
        26.01 megabytes read (20.23 kilobytes per second)
        325.12 megabytes written (252.82 kilobytes per second)
