AL> Hi Robert, AL> I'm not able to reproduce this. What kind of hardware are you on? Ok, lets try on several different ones. 1. XXX, snv_82, 4x 4-core Intel 2.13GHz, 16GB RAM I'm getting about 2k xcalls per second from mpstat. Dtrace nunbers are matching mpstat numbers. 2. Sun X4150, S10U4 127112-10, 2x 4-core Intel 2.66GHz, 32GB RAM I'm getting about 330k-550k xcalls/s from mpstat. DTrace numbers are matching mpstat numbers. 3. Sun T5220, S10U4 127111-10, 1x 8-core 1.2GHz, 32GB RAM I'm getting about 1.7mln xcalls/s from mpstat. Dtrace numbers are about 27k. I'm also getting such numbers on another T5220 with 120011-14. So maybe it is only on Niagara-2 platform?

Yes, I think you are right. On all above platforms dtrace has that impact. -- Best regards, Robert mailto:[EMAIL PROTECTED] http://milek.blogspot.com _______________________________________________ dtrace-discuss mailing list [email protected]
