A few days ago I posted an article about the HP9000/835 TURBOSRX. I had a few problems with a benchmark I wrote for a customer, and it seemed to be that the TurboSRX was really very slow. Now I know that it was not the TurboSRX that was low, but my program. What I did was a make_picture_current call in a loop. Since this call empties the buffer (pipeline) and waits for the TurboRX to finish all it's graphics until moving on with the program, I really took away all the advantages of the TurboSRX with this call. Without this call, the TurboSRX gets all its graphics calls in a pipeline, and they are executed apart from the 835 processor. So with the call my program about had the same performance as a 2397 graphics terminal, and without it the performance increased with a factor 100. There were a few other mistakes in the program, so the overall performance improved with more than a factor 100. Sorry to have mislead you about the performance of the wonderfull machine the HP9000/835 TurboSRX really is, Marco Lesmeister.
