Got a few applications running on here - its a V240 with 4Gb of RAM.

According to vmstat, cpu looks good but there seem to be a high number
of page reclaims and minor faults with regards paging.

Any ideas? Would more physical memory help?

Depends on memory utilization. How much is free?

I prefer to use sar.

My crontab for user sys:
00,05,10,15,20,25,30,35,40,45,50,55 * * * * /usr/lib/sa/sa1
59 23 * * * /usr/lib/sa/sa2 -i 300 -A

Every 5 minutes values for the last 5 minutes are stored.
Close to midnight a summary is created and stored in /var/adm/sa.

Executing sar shows the values from today.
Remember that Solaris 10 does not show waitIO (wio) anymore.
Look at sar -r for memory utilization, sar -d for disk activity, sar -g 
for paging and sar -w for swapping activities.

Dont you enable sar via services now rather than crontab -e?

sar(1M)
     The sar service is managed by the service management  facil-
     ity, smf(5), under the service identifier:

     svc:/system/sar
