Uses a huge amount of memory

[honbolau]

When I use AI extensively in a session, opencode's memory usage will keep increasing until it gets stuck.

This issue might be a duplicate of existing issues. Please check:

• High RAM usage in latest release #2805: High RAM usage in latest release - Reports unusually high memory consumption with Bun runtime after recent updates
• Massive memory use on opening opencode when there is a very large file #2585: Massive memory use on opening opencode when there is a very large file - Reports 29GB RAM usage and slow computer performance, similar memory consumption pattern
• Text rendering is VERY slow (and CPU usage is really high even when idle) #811: Text rendering is VERY slow (and CPU usage is really high even when idle) - Reports high CPU usage (25-30% when idle, 200-300% when active) along with performance issues

yeah current performance leaves a LOT to be desired, we are currently rewriting tui and it should be done this week most likely. It will have a lot of performance improvements.

Not sure if relevant to this issue, but one thing I have noticed is that when I run a debugger and either the server or the TUI stays paused on a breakpoint for a while, I would run out of memory on my system within a minute.

I'm guessing this might be because of messages queuing up and/or this code: https://github.com/sst/opencode/blob/c93c0d402d3130c6e69129395993ac1776132234/packages/opencode/src/server/tui.ts#L12

I'm also experiencing this with v0.15.3.

[rekram1-node]

@dkmnx what kind of project is it? Perhaps lsp servers are eating up the memory

[dkmnx]

@rekram1-node, its a rust project.

[rekram1-node]

@dkmnx is it fixed if you do:
opencode.json

{
"lsp": {
    "rust": {
      "disabled": true
    }
  },
}

Any updates here or suggestions from anyone? In my tiny neovim config directory I am getting large spikes in memory and cpu while streaming in chat responses. I am using WSL.

rewrite ships soon, hard to say what is causing your issue, maybe dry disabling the lua lsp?

{
"lsp": {
    "lua-ls": {
      "disabled": true
    }
  },
}

Oh is it a full rewrite using opentui?

[rekram1-node]

Yes, all the go code will be gone all the core logic stays.

@rekram1-node if I understand correctly, the rewrite is shipped with v1.0? I'm still experiencing debilitating memory usage caused by opencode starting a ton of lsp servers
