Hello all, Today, I was trying to determine the lowest storage size that I could set for one of our test machines. To profile our home grown application, it is not a resource hog, we used to run the same on old AST Pentium 133MHz 64M memory. I have been running our application on our test Linux guest 128M central storage and 128M Swap disk. The machine never swapped when we did some load/performance testing. So following the general guidelines of decreasing the central storage until the machine swaps a little I set the following storage size with the results running some load/performance test:
28M : machine never swapped 64M : Machine never swapped. 48M: Machine swapped a little ( 4M a times) 32M : The machine ran out of memory and failed to IPL .Got the following error. Starting udev: Kernel panic - not syncing: Out of memory and no killable process es... HCPGIR450W CP entered; disabled wait PSW 00020001 80000000 00000000 000884C4 So is it alright to think that 64M with a high speed swap device a good enough setting for the guest? Our Load/performance test was aggressive. We stressed the machine to 5 X the normal levels.
