                          I'm streaming using OBS on Windows (QuickSync), pushing 20k bitrate to 2nd PC based on Linux (Debian Jessie 8.4.0, 64bit) via Gigabit Ethernet.

The Debian system runs a minimal installation without X server (just CLI), where I compiled and installed nginx 1.10 with rtmp module.

Debian Jessie specs:

- AMD Athlon X2 64 4200
- 2GB RAM
- Regular 7200 RPM hdd

nginx.conf:

    root@streamer:~# cat /usr/local/nginx/conf/nginx.conf
    worker_processes 2;
    
    error_log logs/error.log debug; events {
      worker_connections 1024;
    }
    
    rtmp {
      server {
      listen 1935;
      chunk_size 4000;
    
      application transcode {
      live on;
      record off;
      exec avconv -re -i rtmp://localhost:1935/transcode/1234 -c:v libx264  -preset superfast -g 60 -keyint_min 30 -b:v 2800k -minrate 2800k -maxrate 2800k  -s 1280x720 -r 30 -f flv rtmp://localhost:1935/live/1234;
      }
    
      application live {
      live on;
      record off;
      push rtmp://live-ams.twitch.tv/app/STREAMKEY;
      }
    }
    }

My question:
I can stream video using SUPERFAST preset without stutters, but when I go to VERYFAST, video on twitch is stopping every like 5 seconds for a while (not buffering).

Is that Athlon not enough to stream video with veryfast - faster preset? This machine got literally only needed stuff on the CLI Debian just to stream, so I'm not losing any resources.

I was quite sure I can push the quality as faster/veryfast with this rig.

Could anyone elaborate on the topic?
