820169 - Enable system zlib in B2G builds

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: GonkIntegration, defect)

Description

[Justin Lebar (not reading bugmail)]

mwu says in bug 813771 comment 17 that the system zlib might be faster than the one in Gecko.  Since we load lots of zip'ed resources, this might be worth doing.

FWIW I tried this and it was pretty easy. $gonkdir/external/zlib has to be added to the include path, --with-system-zlib added to the mozconfig, and it works.

So, should we do this?

Comment 3

[Michael Wu [:mwu]]

Sure, though we should measure things and see if it speeds anything up like startup or png decoding.
