Issue #1148 has been updated by Hara Hara.

Any update on this? Would be very helpful for newbies to try openIndiana without a install on hard disk

Bug #1148: Serious performance regression using CompactFlash as rpool ( cmdk, zfs? )

I have been using OpenSolaris 134b for a year on several Sun Fire x4540 - Thor systems, booting from Compact Flash slot ( on the back ). No problems with that - performance when booting, altering svcs, anythink is acceptable.

After pkg image-update to OpenIndiana 148, or dev-il ( 151 ), both suffer serious performance regression when using this Compact Flash - it's like 8-10 times slower.

Booting to OS134 bootenviroment - everythings fast. Tried various CF cards - under 134 fast, under 148,151 unusably slow.

Turning sync on rpool didn't help. 

Was there some change in the kernel drivers cmdk or zfs that could cause this regression between 134 and 148?

Attached is complete Oracle Explorer output.

On systems with read harddisks as rpool, OI is great so far.
