Can it go faster?

Is there anything that can be done to improve the throughput?

Using crc I got the following using a folder where all of the files are between 5-7MB each:
-- Done: 756 (4.66GB) Err: 0 (0) Skipped: 0 (0) Tot: 756 (4.66GB) --
-- Average Transfer Rate: 18.94MB/Sec -- Elapsed Time: 4 min 12 sec

Without crc I got:
-- Done: 756 (4.66GB) Err: 0 (0) Skipped: 0 (0) Tot: 756 (4.66GB) --
-- Average Transfer Rate: 36.63MB/Sec -- Elapsed Time: 2 min 10 sec

Is this normal? Or can it be improved on? Windows takes 116 seconds to copy the same path.

XP Pro, gigabit net, Quad core 2.8ghz, 4GB ram.

I find I get better performance using 65K buffer with Flush Buffer checked.

Also, the backup slows down about a third of the way through. Why is this?

Hello

with CRC calculation the copy is slower, because VV needs to read the target file after copying to check the CRC value.

Hello,

- When the speed goes down, is that from what value to what value?

- Does the speed go down also with the Flush Buffer option checked?

- And lastly , does the speed also go down when not copying over the network (i.e. a local disk copy)?

thanks!
