Seeing somewhere between 8-16 here I believe. IIRC I've seen you mention being located in Finland, if so we're probably on the same datacenter in Stockholm. The flows are probably not lasting long because the downloads are split into chunks, which according to my logs are at most 1 MB. Patches seem to work differently, those can be much larger (logs shows the largest one the past months was 137 MB, depends on the game I assume). -- Best Regards, Nils
