Hi @Matthieu,
see Europe server not working - #2 by wm75.
Those 2K Spades jobs (reduced by now to just 200) do not really compete with your jobs in the queue because of the per-user concurrency limit. If you look at currently running tools, you’ll see that this is a happy mix of many different things.
That said, .eu might still not be performing at 100% after this weekend’s update to the latest release of Galaxy, but things are getting better.
