kernel IO schedulers

[Net Llama!]

I could be wrong, but I think that in 2.6.10 there's a choice of several 
different schedulers in the kernel:

# IO Schedulers
#
CONFIG_IOSCHED_NOOP=y
CONFIG_IOSCHED_AS=y
CONFIG_IOSCHED_DEADLINE=y
CONFIG_IOSCHED_CFQ=y

What I'm wondering is what happens if you chose Y for all of them (as 
above)?

The reason I'm asking is that I did choose Y for all of them, and now in 
2.6.10 (but not in earlier kernels) i'm getting some horrific 
performance in X (XFCE specifically).  Scrolling in windows is sluggish, 
sometimes even typing gets lagged.  I'm starting to think that I was 
supposed to choose just one of the schedulers, but I'd like some input.
