[b]How fast[/b] ? What is wrong ? What do you need ?
Did you use 'vmstat' ('page-out' is mostly relevant) ?
Try to get more information
- echo ::memstat | mdb -k
- kstat -c kmem_cache
- swap -s; swap -l
- ps -o rss,vsz,args -e | sort -n
> Could I change this kind of behavior?
1) eliminate swap 'swap -d /dev/rdsk/c0d0s1' (usually 'dumpadm -n' needed)
2) change kernel memory behaivour (in /etc/system like
lotsfree,minfree,desfree,*size*...)

3) try some performance tuning
