Windows 10, SM 2.49.4
Task Manager showed SM using 32% memory with email and one browser window open.
The browser had only one tab with the Washington Post front page. Closing the
browser reduced memory use to 24%; after closing the email then reopening it, it
used only 7%. I've noticed this high memory usage before. Is there a way to
avoid
it, or to reduce it without closing the program? I don't mind closing/reopening
the email, but often I have several windows and tabs open, so it's a nuisance to
close the browser, too.
It isn't just you.
SM has always been a memory hog.
I run it with disk cache disabled, set to 1Mb that is.
Prefetching disabled, check page on every load.
It exceeds 2Gb for me daily, at times spiking to 4Gb.
Thank goodness for the restart button.
The pattern I have noticed indicates not all memory is released when a
page is closed.
If a page takes 150Mb to render, 25-50Mb is not released.
It could be an incomplete release list, or some automatic allocator that
fails to report memory usage correctly.
Not that FF is much better behaved.
No idea on chrome, I won't allow it on my system.
Still better than the mess that is FF.
I am so glad I can kill tabs, I hate those things.
I changed my disk cache from "SM manages size" to 50 MB, and disabled the
prefetch. SM runs much better now, with less CPU and memory usage. Formerly I
struggled to keep the memory usage under 80%; now it remains in the 50s and low
60s. No slowdowns, no more "Not Responding".
