I'm using virtualbox on a Dell D630 (core2duo, 4GB of ram) laptop. I managed to cut 2 hours (yes, hours) of the buildtime by moving lots of stuff to new style staging. With a big tmpdir (6 machines, 2 different archs, lots of machine specific stuff) old-style staging takes eons to stat every file and build a list. Using virtualbox on a 2GB osx machine isn't running so hot because OSX seems to go out of its way to put the VM in swap instead of ram :( regards, Koen -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (Darwin) iD8DBQFLecefMkyGM64RGpERAmLWAJ0dsBhzCnV86Z/rxJKVVGMUS+4q2wCfTPZb ykkNNSvTlPN2ZEIQT8xgfqY= =PZD0 -----END PGP SIGNATURE----- _______________________________________________ Openembedded-devel mailing list [email protected] http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-devel
