Hello ev'rybody,
I have a problem with our system performance under OSF/1 version 3.0. We
develop expert systems using Harlequins LispWorks package as the base lisp.
Under version 2.0 this ran on this machine 3000/400 like a rocket, especially
during compile and when compared to our DECstation 5000/200 doing the same job.
Now under version 3.0 it crawls - the disk is continually grinding. We also
have a machine that runs version 3.2 and it runs fine so I suspect version 3.0
rather than the lisp.
I have run top on the system and am getting the following behaviour.
When quiet - no lisp running although may have been loaded and swapped out -
Cpu states: < 1% user, 0.0% nice, 6-8% system 90ish% idle
Memory: Real: 7-8M/25M act/tot Virtual: 36M/128M use/tot Free 1-2M
When loading/running lisp
Cpu states: 10-40% user, 0.0% nice, 50+% system, 1ish% idle
Memory: Real: 6M/25M act/tot Virtual: 36M/128M use/tot Free < 1M
These figures obviously fluctuate depending on exactly what the system is doing
at the time but the significant figures, to my mind, are the amount of cpu the
system is using and the amount of free memory.
Does anyone know:
1. What I can do to trace this problem?
2. Why the system needs so much of the cpu when the prog is running?
3. Why when only 6M of 25 is in use I have < 1M free - where is the rest going?
4. Is there a problem with version 3.0 or is it the combination of lisp & os?
All help gratefully received - and yes I have talked to Harlequin about this but
they haven't been able to throw any light on the subject.
John.
