But you have reason, I must provide a more formal report. I redid all
with bonnie++ and results shows Linux (56848 K/sec) two times faster than
FreeBSD (26347 K/sec)
Any help will be appreciated!
Linux test (slackware 8.1, kernel 2.4.18, ext2 filesystem):
This test isn't really a fair test either. The ext2 filesystem uses
and doesn't do any kind of journaling to ensure data integrity in the
a crash. FreeBSD isn't using async, it uses softupdates. Because of this
FreeBSD SHOULD be slower... but it'll be a lot more reliable than linux
event of a power outage for example. The ext2 filesystem is extremely
unreliable, and will almost always lose data when there's a crash or power
but then why does read/write tests over raw devices performs so bad?
AFAIK on raw devices not filesystem, journaling, caches, etc are involved.
