Thanks Darryl/David, I am not a native English speaker and wrongly interpret your option.
I have another question: Will bind also help xcall? We have X4440 with mysqld running on it, which has 4 sockets, each socket has 6 cores. There are totally 18 threads in mysqld (we are using thread pool), One of the mysqld thread will doing munmap every 5 minutes to free about 1G memory, and I saw lots of xcall and high syscpu. My assumption is xcall from one node to remote node is more expensive than xcall within the same node because of latency, so xcall across nodes will use more sys cpu (as xcall is in the kernel), so binding mysqld to one socket will limit the xcall to happen within one node which will in turn reduce the cost of munmap. Please correct me if I am wrong. Thanks, Daniel -- This message posted from opensolaris.org _______________________________________________ perf-discuss mailing list perf-discuss@opensolaris.org
