I work with 20+ platforms and often run multiple builds simultaneously from the
same source tree.
It is very important that the large generated files (.o, .so, etc) are stored
on a local disk (as opposed to a NFS mounted disk). NFS writes are extremely
slow. This leads to complicated bjam commands (BBv1, don't know about BBv2)
with -sALL_LOCATE_TARGET=/some/local/disk.
I much rather prefer to cd /some/local/disk once and then repeatedly issue a
simple command, especially since it is then also very easy to find the
generated files.
Cheers,
Ralf
