 |
|
So some sort of Xine optimizer page told me to the following:
| Quote: | | Set HZ to 1000 in /usr/src/linux/include/asm-i386/param.h |
So the kernel is recompiling with this change. What is this going to do?

| It changes the frequency of the kernel's internal timer from the default (100 ticks/second, I think) to 1000Hz. that allows the kernel to shedule tasks in increments of 1 millisecond instead of 10ms. |

Changing that parameter is a bad idea. On my system it actually caused video and music to play slower than it should and the system clock ran slow. Recompiling with the default 250Hz fixed it.
My system is an AMD Barton clocked at 2GHz. Maybe newer systems can handle the higher tick rate. |
