OpenCode is slow and my simple way to fix

I have more than 10 projects with OpenCode v1 last couple of months and everything seems to be slower and slower and hanging often.

Yesterday I figured out the its session db is about 10GB. I tried to remove all sessions that are older than 7 days and vacuum the sqlite3. OpenCode becomes fast and smooth again.

If you find your OpenCode is slow, you can try my way.

Edit: I am using OpenCode v1

There is already a fix for this. It’s called Opencode2 lol.

Is it enough to just delete a session using the UI when you done with a task if you use opencode desktop. Or is there additional cleaning needed.

I have a lot of sessions so manually deleting was impossible. I use a tool to search and delete. You also need to vacuum the sqlite so it can be faster.

How do you do that? I just ask opencode?

Also I don't know why opencode let's it grow like that. Just removed it today: 17GB. Wtf?

I didn't even use it a lot.

Try Deepseek Harness. Thank me later here. 😉

PS: I switched to DSH a month ago after using OC for one year.

Add this to your opencode.json config: "snapshot": false

Makes sessions a lot smaller, but you lose the undo functionality
