I'm sorry to say that actually it was worst than before for me, so
maybe centos kernel is "non collaborative" (eg: no high res timers).

Following is some excerpts from the kernel config (grepping for
obvious words), if useful I can attach the entire kernel config, or
find other informations:

# CONFIG_HZ_250 is not set
CONFIG_HZ_1000=y
CONFIG_HZ=1000
