Yup. You should look at upping those two values until you hit a hitrate
which is acceptable under your disk load.

Unfortunately if you just up them you'll find mysterious crashes as
you run out of sysvshm. src/fs/diskd/store_diskd.h defines SHMBUFS
which is the actual queue size (whereas the q1/q2 determine when
scheduleable disk ops and forced flushing occur..) .. you will need
to up that to be slightly bigger than q2.

And yes, it'll be tidied up before squid-2.4 is released. :-)
