On the Padavan site there are 'two types' of .018 firmware... one has a '1' and the other a '3' (184.108.40.206-018 and 220.127.116.11-018). Difference appears be the kernel version and if IPV6 is needed or not?
With the 18.104.22.168-018 version I was having 100% CPU utilization, solid, even if nothing was happening? Also my transfer rate (as indicated by Windows 7 x64) was about 25Mbps, where as with the .015 drop I was around 100Mbps. On the 22.214.171.124-018 I am seeing the 100Mbps transfer rate. Even thought the CPU Load goes to 100% when this was happening. Transfer done, back to 0%.
