Tryout the terminal command Cat /proc/cpuinfo If this shows processor 0 and a processor 1 the system recognized two CPUs and is using them. The Qsynth through pulseaudio thing is bad as it had (from my experience till pulseaudio 2.0) a bad latency. Use Alsa here instead (needs to suspend pulseaudio first) and test again.
All:
After installing Lubuntu 13.10 (64-bit Mac) on my MacBook, I notice an anomaly with respect to multi-processor usage. I installed gnome-system-monitor (because I like the graph showing internet throughput). On using it on other systems, when it's on a multi-processor system, it shows a CPU-usage graph-line for each available processor. But in this case (even though it has two processors), there is only one CPU-usage graph line. When I checked the "System Tools"..."System Profiler and Benchmark" tool, it showed that it is a dual core (2 processor) machine, and that each processor has a speed of 2 gigahertz. Yet when I later ran Qsynth on it (where it was configured to use PulseAudio, rather than JACK), there were cut-outs in the sound, suggesting that perhaps it is only using one processor. So I am wondering if the Gnome System Monitor is actually correct in showing only one processor? If so, why does the System Profiler show that it is a dual-processor? -- Sincerely, Aere -- Lubuntu-users mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/lubuntu-users | ||
