Re: [squid-users] Squid-2, Squid-3, roadmap

Well, I think that Mark is right on the money here. If there is one
killer app that tops all other functionality additions it would be to
multi-thread Squid so that it can perform on multi-cores. You wanted
input from your users on the -2 or -3 roadmaps here it is. With the
current implementation it is impossible to utilize the hardware to
deliver IO performance across multiple NICs. And Async IO is of little
help. And, as has been pointed out there are other areas besides IO
which would benefit as well.

It is very clear now that multi-core CPUs have become the industry
standard. It is becoming more important every day to take advantage of
the HW that is sitting there mostly idle. With a HW trend as clear as
this, if multi-threading is not very high on the development list by now
then something seems wrong with the roadmaps.
