Why don't you have a look? Monitor the disk activity, there are plenty of tools for that purpose: iostat, nmon, topas, ....
If you want an in-depth analysis about what exactly is going on in your filesystem use "filemon" over 5-10 seconds and analyze its output. Read carefully what the manpage says about filemon, as it is not trivial.
Lacking any further information i would bet my money on swapping though: do an "lsps -a" and tell us what the figures are. Also the output of "svmon -G" would be helpful.
I hope this helps.
