Unfortunately, the positive result was only "short-time": after adapter reboot, which is necessary to activate chosen adapter options, everything was fine, but then after some time (several minutes) ssh session became laggy/with freezes. I tried approach with disabling Large Send Offload and Jumbo Packet as was suggested above (as well as other options in network adapter properties > advanced tab). The described problem was very annoying too. Perhaps there is something about using Emacs in this fashion that is particularly sensitive to network flakiness. I cannot explain why I noticed no network issues with my computer other than when working with Emacs through ssh. My desktop support guy replaced the network cable and the problem seems to have gone away. Since the freezing behavior only started when I moved from Windows XP to Windows 7 I attributed it to Windows, but maybe it is due to a more subtle interaction between emacs and Windows 7.įURTHER UPDATE. Paying a little more attention, this only seems to happen when I am using emacs on the remote server. Since this is happening with two different clients it seems like this must be a Windows issue. I also use RDP to connect to Windows servers without similar freezes, so I don't think it is a networking issue with my machine. So, this is probably not a server-side issue. Others in my group using non-Windows machines do not seem to be having this problem. This happens while connecting to any of a number of servers. No key strokes get through during the hang (not Ctrl-C, Ctrl-Z, or anything I have tried). I have tried both putty and Van Dyke's SecureCRT SSH clients and in both cases I will get a periodic freeze lasting anywhere from 20 seconds to a few minutes. Two different SSH clients are exhibiting a strange habit of periodically freezing or hanging. I am running Windows 7 Professional 64-bit.
