Subject Newsfeed

I have mentioned it before. Every weekend this Newgroup dies
for me and then Monday morning I'm surprised with numerous
messages dated over the weekend and before. As of late I
receive repeated groups of messages, alike a re-scan.

No problem, getting used to it. But this can cause an
uneasyness by getting replies before the question is raised ;)

Where could the bottleneck be ?
