Main process memory consumption greatly increased in 3.32
The main epiphany process's memory consumption went through the roof in 3.32 and continues as such in 3.34. System monitor says it's currently using 1.0G, with only 34 tabs open and with only maybe ~10 of those actually loaded with content, the rest being opened as yet unseen from session. This isn't a leak, it's pretty much at that from application launch. The WebKitGTK web processes are only using ~150Mb each, so it's surprising that the main process is using an order of magnitude more.
I can't remember exactly how much 3.30 was using, but if it was more than a couple of hundred MB I'd be surprised, since I probably would have mentioned it here, and I do remember being surprised at how much more 3.32 was using after upgrading to it from 3.30. As such, it is speculatively a 3- or maybe 4-fold increase compared to 3.30.
I do know that way back when 3.22 was using 100Mb with 72 tabs open, according to an email I sent to the list three years ago. So compared to that 3.34 is an order of magnitude increase again.
