Dear All,

I am going to achieve some kind of real time behaviour by increasing
HZ value in kernel.

I tried to change HZ value in include/asm/param.h.

1. HZ = 1000 --- Response time <3ms
2. HZ = 1500 --- Response time <2ms

I could not go beyond 1500, SHIFT_HZ parameter failed to adjust for 2000.

How can i go beyond 1500 in HZ,

Are there any other way to fine tune kernel to achieve real time
behaviour, other than changing HZ value??

Thank you! in  advance!!
