>From lots of experience, I can tell you that you are just going to have to test it with your configuration. Each version of Mikrotik is different and can radically affect performance. They make so many changes that aren't included in the changelog, you have no idea if they made a change to NAT or not.
Just put PCs on either side of the 532 and run a btest through them. Try with both large and small packets and see the performance for yourself. > Ok guys.
