Tired of having large fsync() times and bad performance when accessing many files in a random i/o manner on big volumes? Do you notice strong latencies where the system seems to be stalled?
Sun published a zfs patch for Solaris 10 SPARC and x86 yesterday. It addresses the fsync() issue which caused me some troubles.
Using filebench varmail, fsync() went down from 1500 ms to 20 ms. The related Sun bug id is 6535160, it was already fixed in Nevada releases and in OpenSolaris. Now you have it for Solaris 10 production systems.
As a side note: There is also a kernel update, 127112-10, which addresses security issues.
The patches will require a reboot.
