rsync algorithm

[hce]

Hi,

I am learning rsync mechanism. My understanding is that rsync reads a
file into multiple chunks and calculates every byte for MD5 and
rolling checksum for each chunk.. On the other side of file system, it
compares two checksums for each chunk in the same file to decide if
two files are equal or not. Is it correct? If it is correct, should I
worry the calculation time if I have thousands large files each
contains 10 MB? Please correct me.

Thank you.

Kind regards,
