Greetings!
New PM user here, currently have x86 26.0.3 installed. I happened to have two windows of PM open, each with 6-8 tabs open to various websites. I noticed in task manager that the PM process was using over a 1.5GB of memory (!).
Seems like a lot. I closed tabs in one window one at a time, with no appreciable change in memory usage, then closed that window. Usage dropped by 200m. Closed one at a time down to a single tab in one window, waited about 5 minutes and the memory usage was sitting steady at about 1.2GB until I closed that window to terminate the PM executable.
Again, new user, but suffered through all of the growing pains of FF as it evolved into a great product. I fired up FF 44.0, loaded the same pages into two windows and the usage is well under 1GB.
I did not see another thread about this topic, so figured it is worth a shot. Any ideas why PM is using significantly more memory than FF?
I appreciate all constructive replies.
Memory management issues in PM?
Re: Memory management issues in PM?
We're aware of some issues with the memory allocator on Windows, causing performance problems and in some cases memory inflation. This will be addressed in 26.1
