Browser Stack isn't usable in Europe, at least, due to latency. As in 'type characters and wait for them to appear on screen' or 'Eclipse' slow. modern.ie originally used it, I hope moving to their own system speeds up responsiveness.
Wait a second... Eclipse as in the naturally-occurring phenomena or the IDE? I just got to view my first partial eclipse two weeks ago and have seen firsthand how slowly the moon creeps across the sun and don't really think Eclipse the software is that slow.
If you're low on RAM (and you will be... Eclipse's Law states that you will download enough plugins to fill all RAM allotted), then the slightest page-in from virtual memory can make typing in Eclipse quite the ordeal. Even if its autocompletion is asynchronous, that's no help when your plugins are thrashing in and out of memory all over the place.
Either. Eclipse the software on a Haswell refresh, 8GB RAM, GTX970 system takes around the same time to respond to a right click on the project folder as the moon does to slowly creep around the sun.
