I have had this issue ever since I started messing with the SSL vpn on the ASA platform. When downloading files via clientless CIFS, if the file is over 2gb it does not download correctly. Before 8.21, it would simply show as a -1 size. Now, it shows as an incorrect positive size, and only downloads that portion(IE a 5.6gb iso registers as roughly 1.2gb, and thats how big the download was). There has to be a way to fix this. Also, I noticed that when testing the thoughput on the webvpn(locally), I get over 20mb/s. This is well below the 100m rated throughput but not bad considering. However, the CPU jumps to 60%+. Shouldnt this be done in hardware not software?
