Bug 30551 – What's eating up all the memory?

• Status: RESOLVED
• Resolution: WONTFIX
• Component: WebKitGTK

Not sure if this is a leak. I'm testing memory footprint for the webkitgtk port. I left about 20 sessions running in separate processes over the weekend and when I came back, only two were left running, and their mem usage grew from 30MB to 600MB while cycling over the same 20 urls while the other 18 processes simply died away. To do this test, I modified the GtkLauncher to cycle through the URLs when the LOAD_FINISHED condition is reached. I tried something similar on the QT port, but didn't get a chance to wait that long to see results. However just cycling through about 5 URLs within a few minute I saw the memory grow to 40MB (http://4.bp.blogspot.com/_JFpJ_4Fo-ZU/StzrnoCXLGI/AAAAAAAAFFM/o1dBTLZ65os/s1600-h/test.png). I've seen it grow as high as 100MBs with more URLs, even though I disabled caching, and set the max cached page in memory to 0 (on qt port only).

Does the webkit memory mean to grow unbounded? If so, are there any ways to limit it throug configuration? I'm looking for a predictable way to run as many browsing sessions as I can in their own processes (private browsing sessions) regardless of size of the pages being viewed knowing that no one browser will be starved of resources. Is there anyway to guarantee this? As in given a certain amount of RAM, I want to know the exact number of active webkit browsing sessions I can run.

Closing this as it's a bit light on details. Feel free to reopen if it's still an issue with later versions.
