Hi
General performance questions if you don't mind regarding CPU and memory? There's a fair bit of info here to hopefully provide necessary detail. Anyway, AIX 5300-06-00-0000, running Oracle, with a little over 11Gb RAM and just shy of 9Gb paging, with 4x 750Mhz cpu's.
Svmon -G:
size inuse free pin virtual
memory 2883584 2882738 846 250487 3280826
pg space 2228224 916708
work pers clnt
pin 250487 0 0
in use 2751363 131375 0
Topas snapshot:
CPU Kernel 24.0
User 75.9
Wait 0.0
Idle 0.0
Network and Disk stats minimal
Memory Real,MB 11264
% Comp 96.5
% Noncomp 4.1
% Client 0.5
Paging Size,MB 8704
% Used 42.4
% Free 57.5
Paging Faults 5414
Steals 0
PgspIn 39
PgspOut 0
PageIn 498
PageOut 78
Sios 378
Now for the questions bit.....
To me, this system is obviously short on memory and CPU but I'm no performance expert. The svmon command says the system is using all available RAM plus 4Gb of paging, with topas showing 96.5% of that being %comp.
1st. Is 96.5% abnormally high or acceptable?
2nd. Paging used is in excess of 40%. Is it still considered too high once you get past about 20%?
3rd. Over 5400 paging faults seems excessive too, wouldn't you agree?
Anyone any comments?
Thanks
