I ran all the tests on two different machines, several times for 1 hour each time. I'm still having a hard time getting
reliableresults for the 30 clients case though. I'm pretty certain the patches bring a performance benefit, but how
highexactly is difficult to say. As for applying only patch 1+2 or all three patches - I found no significant
differencebetween these two cases. It looks like all the performance benefit is in the first two patches.
