Rust analyzer and compilation are very slow. My system is heating up, running out of ram and disk space. I have 8 GB ram.

I use helix editor.

edit: thank you for all your suggestions. I am breaking up the project into smaller crates to see if that makes a difference.

I got the biggest improvements from zram and sccache. With zram my memory usage stays at 90% instead of fully running out when rust-analyzer starts.

    8GB RAM isn’t a small amount (though by no means a lot). As far as RAM usage goes, the amount you need will scale with project+dependencies size, so for smaller projects, it shouldn’t be a problem at all.

    8GB RAM doesn’t tell us about the rest of your system though. What CPU do you have? Is your storage slow? Performance is affected by a lot of factors. A slow CPU will naturally run programs slower, fewer hardware threads means less running in parallel, and slower storage means that reading incremental build data and writing it could be a bottleneck.

      My system has a midrange amd cpu with 6 cores. I have an ssd.

      I think the issue has to do with procedural macros in maud. The project is about 1000 dependencies and 10k loc.

      Combined with tailwind classes and a complex ui, the templates get bloated. I have to test this theory.

        To me that’s a very big project. Have you tried using fewer compilation threads? Maybe you need to sacrifice some speed to make it fit in memory and disk?

        that is too much. i use something with 900ish, and even withh cached builds, it takes like 20 mins, we just have too much linking going on

          Couldn’t agree more here, 1k dependencies would take a while to build even on my 9950x3d if only due to linking.

          It seems to me like the the issue is the project is either too bloated, or large enough to justify a workstation build. Breaking it into smaller, independent parts would also help here.

      8 GB is a really small amount. Even phones have had that much RAM for several years. The average desktop I built in 2012 had 16 GB of RAM.

      Plenty of modern computers only come with a small amount of RAM, because most people only need a small amount, but 8 GB is still a small amount.

        “Small amount” is relative here. Not everybody needs to play Battlefield 6.

        For just programming, 8GB is way more than enough. Even my old work laptop had only 8GB and the issues didn’t show up until I had multiple Office products + Teams + a browser open, not from any of my dev software.
