How does cdc_rsync compare to Courgette for sending a 500MB rebuilt ELF binary where .text and .data now have slightly different offsets ?

- hcs 4y agoI haven't tested but I would guess it's a whole lot faster to compute but will end up sending much more data, given that it only works via exact chunks. A big part of binary patching is finding the largest possible chunks, even if they mismatch slightly. Speaking of Courgette, though, I suggest looking into Zucchini which is faster and often produces smaller patches: https://news.ycombinator.com/item?id=29028534 https://news.ycombinator.com/item?id=29028534 (sorry for linking to my own comment but I haven't found any good explanation or benchmarks from Google)
