Other people have pointed out the absolute uselessness of BogoMIPS for anything and how they are _not_ generic across platforms, so I won't dwell on that. What I don't understand is why you are doing anything other than dedicating that IFL to your Linux/390 LPAR. Are you running multiple Linux/390 LPARs on that one processor? If so, you're probably asking for trouble. During the period of time the server was rejecting connections, what was your CPU load? High? Low? It may or may not be a lack of processor power, but unless you have some data you're never going to know one way or the other. What kind of network connection does this LPAR use? Are there any/many other systems on the same subnet? What kind of collision rate are you seeing? And on, and on, and on. If you don't have any measurements, there's no possible way to tell if your system will be able to handle a real life load or not.

I am currentely testing sendmail (Comparing the load handling between Linux on Intel and Linux on S390. I am using an IBM z37 machine with one IFL and I gave my Linux LPar 80Pwt (processor weighting on the IFL) When the sever gets too busy start rejecting messages. Just for outbount mail and I also want to test for both Inbound/Outbound. What could be the problem here. I will send any further information if it is needed. The following is what I got from my mail administrator. This is the BogoMips rating for the various machines: Mainframe: 326.04 BogoMIPS (Mainframe) Maggie (mail-spool, 500Mhz): 996.14 (Intel) 500meg (processor) Higher is better, BogoMIPS should also be generic across platforms. The mainframe is running very high load and is getting behind with mail. Due to the high load, it starts to block connections which is no good at all (might need to move it back). At this stage I am only running outbound mail through the box, which is not really where the load comes from. The real load comes from inbound mail (300-400 concurrent connections). I don't think this is going to work, unless you can get MUCH faster processors. At least in the range of 2Ghz+ as in Intel architecture. Please assist Moloko
