Currently I am the manager of an ES40 with 4 processors and 8 gig ram.
We run Tru64 4.0f with fibre channel ESA1200 SAN..
We run many oracle instances and the system seems to manage this with no
effort as vmstat and iostat indicate high cpu idle and no actual paging.
However certain types of commands take an age to return e.g.
the ps -ef command tends to pause throughout its completion however the
ps-efl
command completes very fast.
This is just an example of the slow responce I am getting.
Overall the machine runs fairly fast but this is making users believe that
it is an overloaded machine.
Here is an example of the timings for the above commands:-
time ps -ef
........
real 0m10.58s
user 0m0.03s
sys 0m0.15s
time ps -efl
........
real 0m0.11s
user 0m0.01s
sys 0m0.08s
If anyone has any ideas about this I would be more than gratefull....
Thanks in advance
