Question about CPU utilization

Hi, I have question about CPU utilization. My system is a HP UX 11.11 with IDS 10.00.FC5. I heard once IDS is well configured if you have usercpu/syscpu relation of >= 4 in onstat -p. Today I checked my instance and I found a relation of 2 only. My conclusion : There is something to tune ! I checked onstat -g glo and I found high syscpu in 'soc' class, which cause the bad total numbers. Currently NETTYPE soctcp,1,100,NET is used. I tried to move it to CPU, because one single thread is used only. This will shift the high syscpu to 'cpu' but no improvment in total. Furter I tried NETTYPE ipcstr,1,100,NET instead of soctcp. In this case 'str' class shows the high syscpu. Finally I tried to use FASTPOLL feature, but I could not recognize any difference. It looks like the communication protocol keeps the HP system busy. Is there something i missed ? Any ideas ? Regards ... Joerg Rueschenschmidt

It is a test system and no productive system.
