Doubling down on my point from yesterday that we don't care enough about proper OOM management.

I just played around with a giant zram device just see if we can make way more use of compressed memory.

Turns out yes, suddenly my Firefox on Linux holds 250 tabs in memory without any disk-backed swap.

Kinda makes the point that having a fixed-size zram device is a bad idea, and the kernel should just compress as much memory as possible?

One thing I obsess a little bit over is the fact that it’s 2026, we pretend that Linux is a serious OS, but we‘re still losing your data on a regular basis.

Out of memory conditions (OOM) are one of our biggest pain points, so I just did a quick experiment with macOS to see how they are handling OOM.

I loaded about 200 memory heavy tabs in Firefox and kept a close look at memory usage.
