My only question (from risk management) would be: is ASIO tight?
I realize this is unrelated, but: I tried the Bopst Graph Library
(BGL) and our own Spt class for Dijkstra substantially outperformed
it. Then again our Spt is specialized for yielding collections of
abstract route table manipulation commands. BGL is heavyweight on
the theory, and very general purpose. It could be GCC to blame, I
suppose, but I didn't look under the hood.
I have Asio implementations for TSocket, TServerSocvket, and
TNonblockingServer running. Using the stress test, their data rates
are very close to those of the native implementations on the Mac.
(They're much worse on Windows, but I'm testing on a nearly 5 year old
machine running XP>) This is using synchronous I/O though. If I add
read or write timeouts, so that I need to use the async I/O methods,
then the data rate is less. I can't say how much of the top of my
head, because I haven't been doing careful benchmarks. More concerned
with proper behavior.
