From affc8b985a6b059424ae67e230cdc1f1215c9977 Mon Sep 17 00:00:00 2001 From: Scott Rifenbark Date: Wed, 16 Nov 2011 09:42:53 -0800 Subject: documentation: BB_NUMBER_THREADS and PARALLEL_MAKE suggestions Text that suggests setting the BB_NUMBER_THREADS and PARALLEL_MAKE variables to speed build time has been updated to suggest a setting of twice the number of host cores supported. The 2x number came to light through a discussion on the project mailing list initiated by Robert P. J. Day. Reported-by: Robert P. J.

Setting these variables can significantly shorten your build time. -- cgit v1.2.3-54-g00ecf
