This is an unusual problem that I haven't seen reported by others. Is there anything special about your machine, your kernel, your build, etc.? Whether you specify dst_port should not make a difference. This is implemented at a low level, so I don't know why it would change the behavior you

e the increased complexity is a fair trade. We might also be able to improve performance by using native code for some of the work. Were these tests done with the native code JSON parser that comes with OVS? It is dramatically faster than the Python code. > On Tue, Feb 13, 2018 at 8:32 PM, B

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

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
