We're looking into the latency issues, that some of you reported. It's quite possible, that the problem is due to the location of our main server (the one that serves the PAC configuration file). It's located in Germany. Well, it worked quite fast from our office location (which is Poland) while we were testing the app. We will take care of this by setting up multiple locations worldwide with Amazon AWS. This should significantly reduce ping times in US and Asia. Thanks for feedback!
