B2G Firefox Memory consumption MemShrink

MemShrink progress, week 75–76

B2G continues to be a major focus of work relating to memory consumption.  Even the non-B2G-specific improvements made this fortnight were mostly identified and made to help B2G.

B2G-specific

Gabriele Svelto caused dirty freed pages held onto by jemalloc to be purged when a B2G process experiences memory pressure, such as when it goes into the background.  This typically reduces a process’ size by about 2 MiB, so it’s a big deal.  This was a MemShrink P1 bug.

Benoit Jacob prevented the creation of redundant OpenGL contexts on B2G.  This saves 750 KiB in the main B2G process, and 750 KiB in every child that uses WebGL.  Benoit was able to do this based on data from a B2G-specific heap profiler written by Justin Lebar.

I made a large IPC message buffer shrink once all messages from it have been processed.  This saves either 120 KiB or 248 KiB per child process.

James Lal greatly reduced memory consumption of the ical parser during sync.  This change also made it much faster.

Justin Lebar and I added a memory reporter for Freetype, which uses about 2 MiB of memory in the main B2G process.  (This reporter also works on Fennec.)

Andrea Marchesini added a memory reporter for B2G’s gralloc memory.

Miscellaneous

Bill McCloskey made the JavaScript engine clean up more data on memory pressure events.

I increased the size of the chunks used by XPT info’s arena allocator, which saves about 80 KiB per process on 32-bit, and a bit more on 64-bit.

Randell Jesup fixed a PeerConnection leak in WebRTC code.

I added more detail to the JavaScript type inference memory reporters.

Bug counts

Here are the current bug counts.

  • P2: 114 (-5/+9)
  • P3: 103 (-4/+5)
  • Unprioritized: 2 (-3/+1)

After running for awhile my firefox (currently 18B1 but also seen in previous versions) vsize reports around 900MB in about:memory but the private working set is around 500MB (windows task manager) with all tabs closed. This amount never drops… what is missing in the memory reporting that accounts for all of this used memory that never gets freed?

vsize isn’t terribly useful, don’t pay too much attention to it.

As for where the 500 MiB of memory is going… if you copy+paste the contents of about:memory into a comment I’ll have a chance of telling you something useful.

This is with all tabs but about:memory closed.

Next time, consider using something like pastbin instead of posting a massive wall of text.

Justin Lebar and I added a memory reporter for Freetype, which uses about 2 MiB of memory in the main B2G process. (This reporter also works on Fennec.)

Why is this B2G/Fennec-specific?

Just looking Bugzilla and Firefox 18 has a total of 24 bug fixed that have been tagged “memshrink”.

Firefox 19 has nearly double that at 45 bugs fixed. That’s absolutely massive for a project as mature as memshrink.

The introduction of IonMonkey in early to mid January, with this massive load of memory bugs landing on 19th February, and all the time Project Snappy landing bugs as well, it looks like Firefox is going to be in awesome shape in the first quarter of 2013.

A lot of the fixes in FF19 are for B2G, because it’s recently received lots of attention relating to memory consumption. Some of them help desktop Firefox, some don’t. But it’s definitely good to see lots of activity.
