Yes, make that change! You don't need --no-whole-file; it's the default because you're doing a remote transfer. Leaving the old file on the receiver and omitting --checksum has already brought down the transfer time significantly in your earlier test; I bet --inplace will cut the time another 20-40% or so. -- Matt McCutchen [EMAIL PROTECTED] http://hashproduct.metaesthetics.net/ ********//// lsk --> Matt I was doing lot of tests with the real time TTS ransfers using rsync of oracle datafiles. Out of that what I observed was, with the files in place and when I am doing the transfers using " rsync -vz --stats --inplace" it takes more time than deleting all the files in the destination and doing the same rsync. Here is one sample from the multiple tests I performed. 50 GB of data that contains 258 datafiles ******************************** 1) rsync with 150 old files in target + transfeering 108 new files that were not already in destination with --inplace option it took 4:09 2) rsync with no files at target transferring all 258 files with --inplace option without --no-whole-file option it took 3:17 I did tests with some small samples and also large samples than this all shows the following - with datafiles in dsetination takes more time - also inplace saves only abt 10 min max is some cases only ~ 2 min Do you have any suggestions ?
