Hey Alex,
First I want to start by making sure you are not running into this issue we were having last week: take a look at THIS thread.
When you say your office is using 10M bandwidth is that 10Mbps or 10mb/s down? The latter is more than sufficient.
We do not have a paid service, it shouldn't be too long till Method works a lot faster and snappier as we are consistently working on speed gains. Some advice you can pass along to your teams that may help improve the speed.
If you're using Internet Explorer, try Firefox/Chrome. Also opening multiple websites can slow down the speed. For instance, if you are using Internet Explorer for Method and you have 4 other websites opened either in a new tab or a new window in Internet Explorer, this would result in more processes being ran and it can slow down the performance. It may appear as though Method is slow but it actually the browser that is using up the resources. For testing purposes, you can try opening Firefox/Chrome and log into Method and for all other websites use a different browser other than Firefox/Chrome and see if it helps. The speed of your internet connection would also affect the performance. Perhaps, try logging into Method on a different computer and see if the speed is the same. If it is faster, then it could be that your computer itself is slow/doesn't have a lot of RAM.
