FreeBSD – ZFS benchmark

By /

A ZFS CoW (Copy on Write) fájlrendszer, alapvetően más elvek szerint működik, mint a klasszikus UNIX fájlrendszerek. A teszt az említett gépen történt, minden egyéb terhelés nélkül.

vm.kmem_size=768M
kern.ipc.semmni=1024
kern.ipc.semmnu=2048
kern.ipc.semmns=4096
vfs.zfs.arc_max=512M
vfs.zfs.prefetch_disable=1
vfs.zfs.txg.timeout=5
hw.bge.allow_asf=1

A ZIL kikapcsolható, állítólag növeli a stabilitást, azonban lassabb lesz nélküle a fájlrendszer.
