See my update to the comment. Its memory footprint is greater than I expected. I shan’t pursue it any further at present, I was mostly just curious to get an initial feel for it. Taking it (or something like it) to a polished product is something I’d like to do, but I’ve got other, much more important things to do on FastMail and Topicbox, and I don’t think anyone else in the company feels strongly about it, so it’s unlikely to ever actually happen.

One avenue would be to use a different, more light-weight engine; https://github.com/zserge/webview, for example, can use the local platform’s engine, which is likely to be somewhere between a little and a lot more efficient than Electron/Chrome. Running FastMail with the MSHTML renderer via the Rust bindings for that (DPI scaling issues, but meh), it starts at about 60MB but is easy to get over 80MB with some use. Still quite a lot less than Electron/Chrome.

Maybe you can help me understand the outcry over Electron memory usage, especially on HH. I can't remember the last time I ran out of memory on my laptop or desktop unintentionally. Seems to me battery life and jank should be main areas of focus. You can have a 2GB if you cut CPU usage and typing latency.

Just because you "can" use a bunch of memory without issues now doesn't mean you "should" not make any attempts to cut resource usage whenever possible.

Of course you're right. But why does it seem like memory usage takes precedence over battery life and latency? I may be in the minority, but it seems to me a native app's key advantage over Electron is performance/watt and I don't see how reduced memory usage would help.

I've run out of memory a few times this week on my Linux VM at work, and also at home on the beater laptop I use in the living room. Those are both stuck at 4GB of RAM, though.

On my laptop with 16GB, it's certainly been at least a few months since I've done anything that made it hit swap.

I said "unintentionally" as a hedge for corner cases like VMs where you are likely aware of the limits. I probably should have been more clear. I also prefer native apps, which is why I still mostly use Sublime over Code despite the latter's advantages. But it's because of speed and battery life, not memory consumption. If we're going to make a case for native apps, lets at least focus on the biggest pain points, as the proliferation of Electron indicates we're not making an impact.

Battery life's something that I only rarely have to think about. All of my development has always been somewhere with convenient power. It irks me when the CPU's churning along on a process that should be near-idle, though.

I was aware of the limited memory of the VM, but almost everything I run there is a text-mode application, so it usually doesn't matter. Honestly, I thought that Slack would fit easily in the free memory, but I'm logged into 3 teams, so it ate more than I expected. And it's a spinning rust drive; swapping sucks, and it slows down the host OS at the same time.

It's an avoidable situation; just run Slack under the host's Windows, instead of in the Linux VM. But it remains the case, in my uses, that memory has caused more issues than CPU, and that CPU has caused more issues than battery drain. I don't know why everyone else focuses on memory so much...I perceive my own issues as kind of a corner case.
