Hello,
I've seen in the "what's new" of Solaris 10 update 8 just released
that ZFS now includes the "primarycache" and "secondarycache"
properties.
Is this the "equivalent" of the UFS directio?
No. UFS directio does 3 things:
1. unbuffered I/O
2. allow concurrent writers (no single-writer lock)
3. provide an improved async I/O code path
for the record - iirc UFS will also disable read-aheads with directio.
