The times in average goes up 3-4 times and then comes back to normal. I had some hard times with the kernel because at some point it starts to dump stacks for processes that stay too long without responding. Some of the systems had times over 3-4 times going up to about 10 times, but my guess is that it was related to the dumps as the systems get very slow at that point. I'm planning to leave it running again, but disabling the dumps. I'm not really sure it will have much of an effect in terms of performance impact, but I'll try.
