In the course of comparing OS/2 and AIX I've come across another interesting result that hopefully someone can explain. In the benchmark I'm working on now there are 5 programs that are communicating through quesues. One program acts as a receiver and the other four are senders. For each message that the senders send to the receiver program the receive will send a message back to that sender. The results that we got show AIX running 3 times as slow as OS/2. For the test I have five open shells under AIX and five screen groups for OS/2 so the overhead should be similar. I'm beginning to feel like AIX 1.2 may not be nearly as optimized as it needs to be, but I'm willing to give it every chance possible. Anyone have any suggestions on possible speedups for AIX.
