My very cheap home router couldn't handle many connections and crashed 
often. I solved the issue by disabling Hidden Services and now number of 
connections is very low and everything is smooth. (But I have just 
bought a new home router so I'll allow HS soon.) The magic configuration 
line is:

HidServDirectoryV2 0
