No.  It's bits per second.  So it represents how many bits (bytes) are transfered via mudfish program.

Ok thanks, another question, is it better to have higher or lower number of bits being transferred?

> is it better to have higher or lower number of bits being transferred? For most of cases, it doesn't be matter.  :-)  However if its bytes are too high, it means a lot of bytes are transfering via mudfish.  So sometimes it could cause a problem due to network congestion.
