# starting Emacs many times (it was 33% faster on a test with a

# Unlike compile, this is not parallelizable; so if you have more than
-# one core, compile will be (much) faster.
+# one core and use make -j#, compile will be (much) faster.
# This rule also produces less accurate compilation warnings.
# The environment of later files is affected by definitions in
# earlier ones, so it does not produce some warnings that it should.
