Hi all.

I have some questions regarding the performance of various inter-thread
synchronization and semaphore techniques in OS/2 2.0.  (1.3 data is still
probably current).

In particular:

How much time does it take for the system to process DosEnterCriticalSection()
(or whatever the name of the call is -- I don't have the docs handy)?  I
am writing an application that will have several layers, much like a network
protocol stack.  Each one is going to be a thread that works much like a 
filter, managing the packets that are fed through the layers.  How much of a 
hit would I take if I used a critical section whenever I change the structures 
between layers? (assuming each is running in its own thread).  Should I use 
semaphores instead?

Thanks.

PS: any insight into the issues related to this would be appreciated.
