OK, I have the RT-LSM installed, but I'd like to improve the latency of my system. Any hints where to start tweaking the system? Unfortunately, the patches of ingo produce a kernel which doesn't boot on my machine, regardless that I codpied the .config from the vanilla 2.6.14.2. I thought it needs tweaking PAM, but as I understand you correctly, PAM only deals with permissions which I already achieved via RT-LSM. I set HZ_1000 [=y] and (X) Preemptible Kernel (Low-Latency Desktop) in my kernel config, but I "only" get latencies around 16 msecs and still some glitches from time to time. Are there further tricks on a standard kernel I could try to improve latency? Thanks & best regards ce
