What do you think?

This is a very low result :) I don't know your machine or the parameters you used with postmark but even FreeBSD on two striped 7.5 kRPM drives can achieve ~~ 110 tps (so ~~ 50 for a single drive). In the same circumstances and with the right file system - reiserfs in this case - Linux can achieve close to 900 tps (170 tps with ext3). This is the kind of difference I am talking about. A change of 4 tps to 6 tps is not generally useful.
