Hello,
How is it that IOC process only 11000 records per second at AMD Duron
850MHz?
R3.14.5 works at RedHat 8. Database consist of 40000 ai records,
synchronous devAiSoft servers all records, routine increments value
pai->val. if records is scanned with o.1sec interval, then some PVs does
not changes
"if a device causes delays of greater than 100usec
then asyn device support is appropriate." from IOC guide ch.12
Is restriction determinate RTC effect? x86 has worked with 100Hz, 68K has
60Hz?
"68040 IOC can process more then 6000 records per sec" IOC guid 3.2 basic
attributes.
RTC_x86/RTC_68K=1.7 mavPV_x86/maxPV_6=11000/6000=1.8
thank you
Best Regards,
Tatiana
