For what it's worth -- I don't know when you were testing, but with the major increase in the number of computers in the cluster starting about two weeks ago (from 4 to 19), the cloud.sagemath servers are never heavily loaded. More than a few students at a time (e.g., even 20-30) would not cause cloud.sagemath to slow down, unless all students were actively trying to attack the system (e.g., with fork bombs, etc., which would violate the terms of usage -- and so far nobody has done that). Every morning there are typically 150-250 connected clients at any given time, with 30-70 projects often being actively used. This is actually causing very little load on the machines, and they could easily handle 5-10 times that load. Since there's also little bandwidth used in actual sessions, any drag you see with cloud.sagemath is much more likely to be something where cloud is just still slow, i.e., it's not _caused_ by "more than a few students", but by lack of optimization of some functionality. > > A cloud account is great for interested students, and the single cell server > is great for average students or resistant colleagues.
