[ovs-discuss] [OVN][RFC] ovn-northd simple optimization converting uuid from string

2018-02-02 Thread Daniel Alvarez Sanchez
Hi folks, While running rally in OpenStack we found out that ovn-northd was at 100% CPU most of the time. It doesn't have to be necessarily a problem but I wanted to do a simple profiling by running a rally task which creates a network (Logical Switch) and creates 6 ports on it, repeating the

Nice finding! I don't think it's necessary to inline this into the header file to get the speedup, since its caller along the uuid_from_string() call chain is in the same file as hexit_value(). I sent out a patch that does something similar: https://patchwork.ozlabs.org/patch/868826/ On
