HI,
T5220, S10U4 + patches
mdb -k
> ::memstat
While above is working (takes some time, ideally ::memstat -n 4 to use 4
threads could be useful) mpstat 1 shows:
CPU minf mjf xcal intr ithr csw icsw migr smtx srw syscl usr sys wt idl
48 0 0 1922112 9 0 0 8 0 0 0 15254 6 94 0 0
So about 2mln xcalls per second.
Let's check with dtrace:
dtrace -n sysinfo:::xcalls'[EMAIL PROTECTED]();}' -n
tick-1s'{printa(@);clear(@);}'
dtrace: description 'sysinfo:::xcalls' matched 4 probes
dtrace: description 'tick-1s' matched 1 probe
CPU ID FUNCTION:NAME
24 47924 :tick-1s
28274
24 47924 :tick-1s
27808
24 47924 :tick-1s
27721
24 47924 :tick-1s
27736
^C
less than 30k per second.
I guess dtrace output is more reasonable but I'm not sure.
Why the difference?
