Lies, damn lies, and benchmarks. ;-) Seriously though, I'm not clear on what you are measuring or how you are measuring it. It looks like this is measuring signal latency, which is important, but what about thoroughput? --Chris - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
Signal Handling Performance?
I am doing a research project on Linux kernel performance starting with the 2.0.1 kernel through the 2.4.0 kernel. I ran across something very interesting when running LMBench and reviewing the results. The performance of Signal Handling has decreased while every other area has either stayed the same or had a performance increase. A general decrease started around kernel 2.1.32, then performance drastically fell at kernel 2.3.20. There is an Excel graph which shows the trend at: http://euclid.nmu.edu/~benchmark/Carey/signalhandling.gif I was wondering if anybody had any ideas why this is happening, and what happened in kernel 2.3.20 to cause such a decrease in performance?
