Difference in Download Performance Rates Between Binary Files (IE mysql ibd) and Txt file

Hi !

i would thank you if anyone could clarify this to me .

im testing passing traffic from one DC to another DC .

if the file is a text file ie: SpeedTest.txt , i can download in about 20MB/s  .

if the file is a binary file ie :SpeedTest.ibd (mysql) , i can download in about 2MB/s .

all tests were made using Rsync on Linux Machines . ( but it also happens with scp/sftp etc )

so i guess its something with encoding or perhaps hashing that is make per "chunk" ?

what is this happening , and if you know , what is the best way to pass binary files ? ( i use rsync because it use multiple sessions thus faster )

Thanks A lot !
