...them on 2 different cores, there will be xen_evtchn_do_upcall() existing (maybe when the local_bh_disable<http://www.cs.fsu.edu/~baker/devices/lxr/http/ident?i=local_bh_disable>() or local_bh_enable<http://www.cs.fsu.edu/~baker/devices/lxr/http/ident?i=local_bh_disable>() is called) in __inet_lookup_established() routine which costs longer time than the first scenario. Is it due to the synchronization issue between process context and softirq context? Thanks for any reply. 1) | __inet_lookup_established() { 1) | xen_evtchn_do_upcall() { 1) 0.054 us | exit_id...
