before running the tests multiple times to confirm that this indeed is the case...
before looking into the recent changes...
before looking into the test code...
before checking if swap is being used...
before checking if logging is enabled...
before doubting the kernel upgrade...
before using strace -c to find out unusual system calls...
before using valgrind --tool=callgrind to profile the code...
The first thing to do is to check cat /proc/cpuinfo and check in cpu Mz is same as advertised cpu speed. Laptops usually run in power saving mode. Not sure what is wrong with 64 bit Ubuntu 11.04, running on Lenovo Thinkpad T410. Even with power plugged in, it decided to run at 933Mz instead of 2.53 Gz.
