It's in 10.2.2.
JFS is there in 10.2.2, they have only made it a feature that htey are speaking of in 10.2.2 server however. Do you really believe that Apple would put an unredy hack to the FS as an advertised feature for a aerver OS? Also, I have enabled JFS on both my Macs and the performance hit is so negligable that I do not even notice it. That may be because I have a lot of RAM but whatever the reason the performance hit is overstated.Originally posted by itanium
I don't believe in its finished form. Especially with a 10-15% performance penalty.
Hopefully 10.3 will move away from HFS+ completely. There should be no performance penalty then.
