Let's Talk DD !
I have experienced major performance issues with DD and cannot find valid justifications for that.
Playing with many different parameters (bs, nosync, noerror, ...) I have always fairly much the same results:
- First few seconds are 3.4 GB/min
- Then massive drop down to 50 MB/min
- Copying NULs does not reproduce the above symptoms and speed is stable at 3.4GB/min.
I see in blogs that I am not the only one with this issue but cannot find an answer...
