Closed Bug 857806 Opened 7 years ago Closed 6 years ago
Memory consumption increases to 2
.4 Gi B over a week (w/44 extensions enabled)
User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:19.0) Gecko/20100101 Firefox/19.0 Build ID: 20130307122351 Steps to reproduce: Opened some tabs, browsed normally, left it open for a week. Actual results: Memory increased to 2.4 GB or so. Expected results: Memory should have stayed constant at around .5-1 GB.
At a glance, this part looks the most suspicious to me: ├────692,717,904 B (65.95%) -- layout │ ├──489,972,528 B (46.65%) ── style-sets │ ├──104,415,960 B (09.94%) ── frames I'm not sure what "style sets" are, though.
Style sets are CSS stuff. More suspicious is the fact that there are more than 30 http://www-ig-opensocial.googleusercontent.com/gadgets/ifr?exp_rpc_js=1... windows, each of which contains 3 compartments. I wonder if there's a leak there. This is also interesting: 2,183 (100.0%) -- js-compartments ├──1,109 (50.80%) ── system └──1,074 (49.20%) ── user That's a lot of system compartments. Oh, but you have 44 extensions enabled! That's a lot. 621 of the system compartments have "bootstrap.js" somewhere in the name, so extensions explain that, I think. But really, we need an about:memory diff to make sense of the increase. Roll on bug 848560...
Depends on: 848560
Summary: Firefox uses too much memory → Memory consumption increases to 2.4 GiB over a week (w/44 extensions enabled)
Bug 848560 has landed. Thanks for waiting. Can you update to the latest Nightly and use the "Write reports to a file" button at the bottom of about:memory to take measurements before and after? Thanks!
Now running the nightly, I'll upload some dumps if/when the memory usage spikes.
The memory usage has been reasonable for quite a while... closing.
