From 464e0d5ed87f5e0c7fa10d13075e62307eba075f Mon Sep 17 00:00:00 2001 From: Martin Sustrik Date: Tue, 17 Apr 2012 10:48:59 +0200 Subject: Improve efficiency of time measurement in tight loops This patch instantiate a clock_t instance for each XS socket. Thus, it is shared between subsequent calls to xs_recv (and xs_send). That in turn significantly limits the number of invocations of getimeofday (or similar) when timeouts are used and recv/send is called in a tight loop.
