Building for my kernel and timing the various steps, e.g. % time bitbake virtual/kernel -c compile My kernel: compile 1m49s deploy 0m16s populate_sysroot 0m38s package 23m20s" https://lists.yoctoproject.org/pipermail/poky/2011-January/002635.html This performance impact may have been introduced by recent changes to the package.bbclass to use the rpmdeps command to discover per-file dependencies. http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=54e3a82d9c14f3071db4a4f78312c0e31534696c 11536 1 josh 2011-01-20 09:19:04 +0000 A second theory is that the bitbake package/server split is causing a lot of context switches for the messages, during package creation - particularly for large packages like the the kernel.

We've increased the size of the pipe and performance improved dramatically. 14990 3 josh 2011-07-25 08:27:04 +0000 Verify fixed
