If the behaviour-difference is clear, you could try to bisect this. The alternative is to use your favourite system profiler and see where the cycles get wasted (either sysprof or perf). I suggest you'll try whatever approach your more familiar with first and then switch over to the other if the first one doesn't yield any clear results. If the difference is really clear, I'd start with the bisect (aside: don't restrict the bisect to any subdir, the change causing the regression could equally likely be somewhere in the core kernel).
