Hi I installed FreeBSD 4.9RC1 on P4 3GHz with hyperthreading and I see drastic slowdown when kernel with hyperthreading is booted. For example program compilation took this time:
hyperthreading kernel, make -j 1 --- 1:09 hyperthreading kernel, make -j 2 --- 0:42 singlethreading kernel, make -j 1 --- 0:45 singlethreading kernel, make -j 2 --- 0:41 Compilation does very few system calls so when I compile with only one process (-j 1), it should be as fast as with singlethreading kernel. Do you have any idea why is it so slow?
