Response time is slower than expected (or possible incorrect)

My local setup im testing this with is a golang fiber server

When i make a request with other HTTP Clients (such as insomnia) or my browser it shows very low latency (of under ~12ms) of request time, but Yaak shows ~300ms consistently, all other tools from my testing seem to not show such long response times

I’m unsure if this is a bug or not but i think this should be investigated at least

I’m seeing the same on Linux, although only in 2026 versions.

For a small request that takes 18ms using curl, I’m getting around

30ms in 2025.9.3
300ms in 2026.1.0
600ms in 2026.3.1

The timeline tab shows that sending and receiving each header takes like 20ms, and a 300 byte body takes 100ms so something’s definitely horribly wrong

I wonder if this is from a slow disk, as each one of those events causes a write to Yaak’s database. What type of hardware are you running on?

9800x3d, 6000mhz ddr5 ram, nvme 3.0 ssd, so I doubt it.

I did some rudimentary debugging and I can definitely see it’s something related to writes. When I hardcode persist_response to false, all the delay goes away (I check this by printing time elapsed in rust, can’t see it in the UI because it just keeps “CONNECTING” forever). I can try debugging it further if you give me some pointers.

By the way, I’ve created another post on this issue: https://yaak.app/feedback/posts/requests-getting-slower-in-newer-versions
