From ba480730dc2759aad76729102400b2265eb87aac Mon Sep 17 00:00:00 2001 From: Michael Brown Date: Tue, 26 Jun 2012 12:42:06 +0100 Subject: [PATCH] [cmdline] Increase resolution of "time" command A reasonably large (512MB) file transferred via HTTP over Gigabit Ethernet should complete in around 4.6 seconds. Increase the resolution of the "time" command to tenths of a second, to allow such transfers to be meaningfully measured.
