I am working with ffmpeg over LAN.
I want to MERGE 2 files.
1 AVI with huffyuv and
1 WAV with pcm_s24le
to one file (AVI) with a video and a audio stream.

If I do this from HardDisk to LANshare it takes more time than a simple 
filecopy of both files to the same target.

Filecopy: 80 percent LAN speed
Merging: 25 percent LAN speed

On the left side you can see the filecopy- and on the right side the 

Is it possible to speed the merging up in any way?
Does the ffmpeg merger has an internal bottleneck (?)

command line:
ffmpeg -i inputfile.avi -i inputfile.wav -acodec copy -vcodec copy -map 
0:0 -map 1:0 \\lanshare\folder\targetfile.avi

Best Regards
