worsening performance

Hi,

Good to know, I was hoping so.
But still I wonder why rather smoothly running traffic drops
with such a sharp cut, there must be a reason for that. 
Certainly, on the larger scale, this behavior reduces overall 
performance in the Tor network quite significantly.

During the last 90 minutes though, traffic on my node shows again more 
normal patterns.

If this is due to the time of day (don't ask, but it is evening here) or
 someone with the right time has flushed the right cache, I do not know.

Regards

Hans
