It can be difficult to tell without some sort of instrumentation or analysis of how Linux is performing. At the first hint of a performance problem, the typical solution in the Intel world is to throw more or bigger boxes at it. We don't always have that luxury in the 390 world. Therefore alot of shops have monitoring tools to tell us where the problem is so that we can come up with a game plan on how to fix it.
Running in an LPAR you are somewhat limited in that you can only use Linux tools and the HMC displays. I do not know what monitoring packages exist for Linux (besides top), that will give you the information that you (and we) need to work this out. Of course under VM there are a number of choices. While you are testing sendmail, what does the HMC indicate about the CPU load if your IFL? Also, does the IFL use dedicated CHPIDs to the DASD? If so, what is their utilization? As mentioned earlier, try dedicating the IFL to this Linux partition (as long as there are no other LPARs that need it).
