[WBEL-users] performance of update 1 slow

[Tom Brown]

OK - thanks all - I've updated to the megaraid2 driver, we are using this
already on some new Dells with PERC4 cards but this particular machine is
running a PERC2
I'll see how we get on but unless i get a decent improvement i think i'll
have to go back to 7.3 for this particular machine.

It definately seems to be driver related though i think - there are many
discussions it seems revolving around RHEL and megaraid performance issues

thanks
