As lots of other people have already said (and with whom I agree), you really need some sort of performance monitor to figure out problems such as this. One thing I will say regardless of that, is that it looks like you have almost half a gig of inactive pages in your guest. That means that you can likely reduce your guest size by about that much (subject to subsequent measurement of the results), and see if your Linux paging rates go up a whole bunch. The fact that your system is using about 1GB of storage for caching tells me that likely they won't. (And, don't confuse page space in use with paging I/O _rates_. The first is OK, the second needs to be watched closely.) Doing this is not likely to have an impact on your immediate problem, but keeping your guest sizes as small as possible is a good habit to get into now. Second, since this is a brand new install, why are you using SLES9, and not SLES10? ISV certifications and such is a perfectly good reason, of course, but if there's nothing like that standing in the way, I would recommend using SLES10 SP1.
