you can fast-scroll through millions of notes in notedeck and watch the memory usage go into multiple gigabytes.

the cool thing is that the type of memory notedeck allocates is "virtual", which means if there is memory pressure on your system, the OS can freely discard 95%+ of notedecks memory usage without paging it to disk and without any impact on performance. don't be discouraged if you see high memory usage, it won't have any impact on your system.

it seems activity monitor doesn't show this virtual memory usage unless you're looking at the "real memory" column on macos, so you may not even notice it. memory can be confusing sometimes...

at most notedeck should only use 100-200mb of fixed ram, but this isn't optimized at all and we can get it down further. bloated software is everywhere and is getting worse, notedeck won't contribute to that!

thanks for coming to my ted talk.
