I'm wondering if this will slow down rsync. Since the function changes the size of the file before rsync writes out the data, does this result in extra disk I/O, especially for large files? We'd probably need to test both Windows systems and Linux/unix systems separately and possibly conditionalize the code (it it does not slow things down somewhere) or make it a configure (command-line?) option (if someone wants to pay the price for reduced fragmentation). ..wayne.. -- To unsubscribe or change options: https://lists.samba.org/mailman/listinfo/rsync Before posting, read: http://www.catb.org/~esr/faqs/smart-questions.html
