did you actually capture the traffic counting the process time spending on a single packet IN and OUT of the system? Maybe you can try to install a factory driver of the network card to see if it's helpful. First of all, better figuring out where the problem is. Kernel itself or driver. To openvpn, you can use strace for a single connection test. But capture first. ------------ Banyan He Blog: http://www.rootong.com Email: banyan at rootong.com On 3/27/2013 9:39 PM, John Doe wrote: > Hi, > > after a long general power failure, I had to power off/on my > > soon to be 6.4 firewall (updated to 6.4, but not rebooted yet). > After the off/on, everything seemed to be fine. > But I realized there were some specific/weird heavy slow downs. > In one case, the windows clients *uploads* would stall (very slow), > > while the linux clients had no apparent upload issues...
