That has absolutely nothing to do with his problem. In fact having a smaller maxpoll saved
him sooner from whatever destroyed his time. Note that he is running a vm and the time on
a vm is terrible. To have this number of sources and then to run on a vm is a bit of
insanity but it won't hurt, just as his non-efault maxpoll also will not hurt him (it may
increase the load on the servers a bit)

Agreed. That like is not needed.
