SABnzbd Forums

So I'm getting a max speed of 25 MB/s with sabnzbd but when I use grabit, newsbin and others I get about 80 MB/s. I done everything here but it made no difference

That could well be the upper limit of SABnzbd on your hardware.
SABnzbd, written in Python, is simply slower than its C++ written competitors.
