Hi,

I have problems with the performace of my Server,especially with the yield the CPU, The server is a HP R390, whith 1,9 GB RAM, and one procesador, SO, HPUX 11.00.

My question is since I do in order that some processes do not consume the total yield of the CPU,

Attach the configurations.
forgive the English I read it but almost I do not write it, hope that they understand me Thank you
