Hi, Chris, As far as I know, the mutex implementation in Linux is based on futex already.
Thanks, Haitao -----Original Message----- From: dev-return-1553-haitao=openailab....@mxnet.incubator.apache.org [mailto:dev-return-1553-haitao=openailab....@mxnet.incubator.apache.org] On Behalf Of Chris Olivier Sent: Friday, November 24, 2017 3:02 AM To: dev@mxnet.incubator.apache.org Subject: Futex Was doing some timing with futexes (we used them a lot in a previous life in database engines) and they're consistently about 20-30% faster than standard mutexes in Linux. However, it seems like this is not worth making a change since mutexes don't tend to get called so much that it would seem to make a noticeable difference, although I could be wrong -- so far besides the queue, I am not aware of any major bottlenecks on mutexes. Any thoughts? -Chris
