rsync performance test

[Yatin Manerker]

Hi, 
 I am working on testing of rsync on  SLES10  (2.6.16). Currently I am
looking for test parameters for testing performance of rsync. Has anyone
done performance testing on rsync ?  If yes, can u plz let me know. 
 I was planning the following test:
Test 1:  Total data size is 1GB. And 10% of the data is modified. How
much time rsync will take to sync the data after modification ?


Regards,
Yatin
