File Transfer Slow With EXE Files

mutantworm · Post by **mutantworm** » 2013-04-26 19:39

I've noticed that file transfers in UltraVNC are extremely slow when transferring exe files compared to other file formats. Why is this and is there a way to get around it? It seems putting the files in a zip file does not help either. For example, I can transfer an mdb file at around 300 kb/s, but an exe file will only transfer at 50 kb/s.

Thanks for any insight.

all data is compressed / decompressed.
exe/zip recompress bad

I see how compression affects the overall size of files, but how does compression affect the actual transfer rate of files?

I try again...

Uvnc compress FT data before sending it.

If uvnc compress 1mb to 100k you only need to send 100k you send a 1mb file in 1 second : speed 1mb/sec
if uvnc compress 1mb zip you still have 1mb and need to send 1Mb -> 10 seconds: speed = 100k/sec

Also, compressing a already compressed file takes longer then a non compressed.
