hi All, recently we were developing high performance / low latency transaction processing system with Linux. (i.e. SuSE 11 but 2.6.29 vanilla kernel) we tried to send high volume of traffic, typically 20K messages per second. each message is about 400 bytes to 800 bytes. we saw ksoftirq thread is taking about 19 % CPU at 15K rate and at 20K rate it was about 100%. so we could not pump messages more than 20K. do you guys have any idea about ksoftirq behaviour, why is it taking 100% CPU. we have tried both 1G NIC and 10G NIC. we saw high % for both NICs ? cheers __ tharindu -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
