We have performed recently an upgrade from Solaris 11 Express 11/10 to the release 11/11 (following the upgrade procedure)
However, we have throughput issues on the filesystem
- On some regular task such as compiling, there is a 2 folds increase in time
- We have also an Oracle DB 11g running and its worst than that, there is nearly a 6 folds increase in time (for some benchmark)
The behaviour has been checked a few times with the previous Express kernel
There was no hardware change on the target host.
We just use ZFS has a "regular" filesystem: no raid or any fancy feature use.
We had a look to the configuration of caches on the ZFS side, and there is nothing special or any tuning (except 2GB for arc_max).
Caches are active.
AHCI is active.
