dolozit, jak jste k tomuto zaveru dosel?
Jinak to vypada takto (verze 4.22):
 
            Context [microsec]     Interrupt latency [microsec]
P133           3.1                        4.3
P100           3.9                        4.4
486DX4         5.1                        4.9
386/33        25                         14
