Our system is also getting killed by async output. We run a 3/180 with an ALM-1 (16 line MUX) and a small number of users on screen-oriented programs. Serial interrupts appear to be the culprit. We are working on the programs to optimize their output, but that is clearly not enough. My question is: does the ALM-2 offer any improvement or are there any third party devices that can offload the CPU a little better?
