I get the same numbers more or less. Note that zyre perf code is less optimised for throughput - it uses high level APIs that do a loc of mallocs and copies, etc. libzmq perf code uses more high performance zero-copy APIs, and that makes a lot of difference. > 2017-08-10 12:55 GMT+02:00 Luca Boccassi <luca.bocca...@gmail.com>: > > On Thu, 2017-08-10 at 10:43 +0200, Francesco wrote: > > > Hi all, > > > > > > I've been looking into Zyre as framework to build peer to peer > > > messaging. > > > I've found that there is a "perf_local" and "perf_remote" > > > binaries > > > inside it...
