Hi, In Freebsd 10.0-current with Emulex's OCE driver, I observe that the bottom= half is hogging all the CPU which is leading to system sluggishness. I use= d the same hardware to check the behavior on 9.1-RELEASE, everything is fin= e, bottom half is not taking more than 10% of the CPU even at the line rate= speed. But with half the throughput of line rate in Freebsd-10.0-current a= ll the CPUs peak and "top -aSCHIP" shows that it's all bottom half who is e= ating the CPU. Did anything changed in Freebsd-10.0-current that I should b= e careful about? Please clarify. Thanks, Venkat.
