Re: threading

Peter,

My assumption was that this was on the ServerSide of IIS, otherwise I would
not have given the same solution as Jon did, however, he did already..

AFAIK that the computer is processing with 10 active users at least 110
running threads at the same time, will this not give a bunch of overhead?

Nothing about Jon's suggestion would cause that overhead, regardless.

You seem to be making the assumption that the OP is writing code that will
be server-side for a web site, and which could start ten different threads
per user, with an eleventh thread for each group of ten managing them.

I don't see anything in the original post that suggests this is the case
(sounds more like a single-user application that connects to ten different
web sites). Even if it were the case, you've also made the assumption
that all 110 threads would be running at the same time. But that would
only be the case for a CPU-bound algorithm. Most of the stuff computers
do isn't CPU-bound, and it's easily possible that only a small fraction of
those 110 threads would actually be runnable at any given time.

Of course, depending on what the OP's threads are doing, it's possible (if
they are just doing i/o with some web sites) that he would be better off
using some of the built-in HTTP communications features of .NET, along
with the async methods on the supporting classes, thereby eliminating all
of his threads altogether. But that's yet another entirely different
issue, not one that he's asked about yet.

But in any case, regardless of any of those other issues, none of that has
anything to do with Jon's suggestion. His suggestion doesn't introduce
any new threads to the equation at all. In that respect, one could argue
it's among the most efficient ways to deal with the particular question at
hand.
