Problem with latency after upgrading

I upgraded my dist and the kernel version 2.6.21-1-multimedia-amd64 was installed. The only good thing about this was that I was able to install the nvidia driver. The latency got worse and I was not able to record anymore (no input signal from the pre-amp/mic). When booting with the old kernel 2.6.17-1-multimedia-amd64-k8 the recording works excellent and the latency is very low (I can even configure jack with 0,726 ms using 16 frames/sec, 44100 sample rate, 2 periods/buffer). Has the older kernel really lower latency? Do I have to configure the newer kernel? Should I try installing version 2.1 from a dvd/cd image rather than upgrading?

You have hit the nail on the head. Later kernels have worse performance, and the kernels that came after our 2.6.21 was even worse.
