Hi, I''ve let my test system (laptop with 1.5GHz Pentium-M) run kernel compiles for most of the afternoon and the early evening. I''ve ran with both TLS in place and moved out of the way, rebooting between the tests. I''ve taken the best time out of the series, making the assumption that the worse times are caused by interference of other things on the system. The best kernel compile time without TLS: real 11m14.776s user 10m8.540s sys 0m49.810s The best kernel compile time with TLS: real 12m30.661s user 11m21.730s sys 0m49.460s Difference: 1m12s, or 11% slower. This is all running today''s Xen and xenolinux (from bk) and compiling linux-2.6.8.1-xen0 with the defconfig from bitkeeper. cheers, Rik -- "Debugging is twice as hard as writing the code in the first place.
