What the best practices for choosing ZFS volume volblocksize setting for
VMware VMFS-5?
VMFS-5 block size is 1Mb. Not sure how it corresponds with ZFS.
Setup details follow:
- 11 pairs of mirrors;
- 600Gb 15k SAS disks;
- SSDs for L2ARC and ZIL

tmpfs in Solaris is backed by virtual memory.
It is like a RAM disk, although maybe slower than ramdisk

You care about #2 and #3 because you are fixated on a ZFS root
lock contention problem, and not open to a broader discussion
about what your real problem actually is. I am not saying there is
not lock contention, and I am not saying there is - I'll look at the

As a random guess, try pointing PHP tmp directory to
/var/tmp (backed by zfs) and see if any behaviors change?
Good luck,

Thanks for your suggestions. Actually the default PHP tmp directory
was /var/tmp, and I changed /var/tmp to /tmp. This reduced zfs
root lock contention

Zero correlation.
