I am using glibc 2.3.6 (pthreads + libidn) compiled against kernel 2.6.12 headers. If a process needs 100% CPU power the latency is becoming terrible. If i nice that process to a lower priority effects are not that strong. Especially working with a web browser displaying a website where multiple flashplayer-plugins were startet the system is almost unusable. Input events are not catched, mouse and sounds stuck and so on... Preemption model is "low-latency-desktop", CONFIG_PREEMPT_BKL: 1 CONFIG_HZ: 1000 Has anyone experienced similar problems?
