Subject: High csrss.exe utilisation on XP with legacy software
I'm serving RealVNC Free Edition 4.1 from an XP32 SP3 box. When I
run legacy Turbo Pascal programs from the client the csrss.exe
utilisation jumps up to 100% on every keystroke (or even if the
application is put in foreground) for several seconds and sometimes
as long as a minute or 2. This stalls things and makes the session
unuseable. The Turbo Pascal programs don't generate much screen
traffic as it is mostly file shuffling so I don't understand why
csrss is getting so much utilisation.
Anyone understand this and/or have a fix or workaround? It's a big
job to redo the legacy stuff. (Clients are XP or W7 machines and
all demonstrate the problem).
Thanks.
Robert:
Most DOS programs consume 100% of CPU cycles in a Windows box. I'm
guessing this happens because DOS had no built-in
process-scheduling or process priority, but I don't really know for
sure. U might want to look for old TSRs that could interrupt the
CPU and execute a halt instruction. I recall that there was one
called "Rain," or something like that. Again, this is only a guess.
Thx, P.
