- `ENABLE_GZIP`: **false**: Enable gzip compression for runtime-generated content, static resources excluded.
- `ENABLE_PPROF`: **false**: Application profiling (memory and cpu). For "web" command it listens on localhost:6060. For "serv" command it dumps to disk at `PPROF_DATA_PATH` as `(cpuprofile|memprofile)_<username>_<temporary id>`

1. Enable pprof in `app.ini` and restart Gitea
```
```ini
[server]
ENABLE_PPROF = true
```
2. Trigger the bug, when Gitea gets stuck, use curl or browser to visit: `http://127.0.0.1:6060/debug/pprof/goroutine?debug=1` (IP is `127.0.0.1` and port is `6060`)
