Justin Lebar led the B2G charge this fortnight, doing the following.<\/p>\n
Thinker Li identified that we were using overly large (128 KiB) arena chunks for type inference data in the JS engine<\/a>.\u00a0 Reducing them to 32 KiB saved over 3 MiB of memory on B2G.<\/p>\n Fabrice Desr\u00e9 disabled the add-on manager services<\/a>, saving about 1 MiB.<\/p>\n These changes have all been backported to Aurora, because that’s the current home of the code that will be used for the V1 release of B2G.<\/p>\n Jared Wein modified the social sidebar so that it unloads itself 10 seconds after it’s been hidden<\/a>.\u00a0 This is good because lots of people thought that closing the sidebar was equivalent to disabling the social functionality, and with this change it now effectively is.<\/p>\n Felipe Gomes fixed a major problem which caused the social API to create and leak many unnecessary ports<\/a>.<\/p>\n Benoit Jacob fixed a leak relating to WebGL and cycle collection<\/a>.\u00a0 This fixed 10 seconds pauses that occurred after running the RO.ME demo<\/a>, and also fixed leaks seen in the WebGL version of Nokia Maps<\/a>.<\/p>\n Kyle Huey fixed a bug that was causing storage code to leak one thread per connection<\/a>.\u00a0 This doesn’t affect most Firefox users much, because most connections live for the full lifetime of the process.\u00a0 However, it could affect some add-ons, and it helped avoid some frequent OOM oranges in some of our tests.<\/p>\n Benjamin Peterson reduced the amount of memory used to compress JavaScript source code<\/a>.<\/p>\nSocial API<\/h3>\n
