We have 2 servers both running redhat enterprise 4.7 bigsmp kernel 2.6.9 + redhat patches. one has 40GB the other have 64GB.
Same processors, mostly same config.
We have compiled perl ourselves v5.8.9, same binary on both servers.
Profiling our perl app shows that the 64GB is twice as slow regarding perl. For binary data is it around 20% slower. We mostly takes lots of strings and create a large object of them.
I'm investigating further with redhat, but I'm wondering if any of you have seen similar behaveour when it comes to 64GB.
Thanks
