[LAU] Amazing improvement recompiling a kernel

I just saw some amazing improvement on this laptop (2GHz, 2G RAM, dual-core, >5 years old) by recompiling kernel and glibc in Debian Testing (Jessie) with optimizations for this CPU. Overall responsiveness is wonderfully better, 48 KHz began working well, and stability arrived at 5.33 ms latency in Jack (previously 15-20ms...). The current Debian Testing made the glibc recompile much more straightforward than I've ever seen it, and I have written it up here: http://notes.ponderworthy.com/rebuild-glibc-optimized-for-your-cpu-in-debia… I don't usually go quite that deep into sysarcana, if any of you out there have improvements I'll love to have them and will make sure readers know where they came from if desired :-) Cheers to all!!!!! -- Jonathan E.
