| |
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:

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?
Thanks for your time Carey Stortz
