Hi there,

I just gave 7.2alpha5 a try. In general it has almost equivalent
performance than 7.2alpha4 but on one benchmark (beval), it is
significantly slower. Have you noticed something similar? Do you have a
regular benchmark that would let us compare the different versions of
the collector. Thanks in advance.
