 No the other way around... Higher (driver/cpu) throughput/load causes more 
 dst-entries to freed and you reach the max_size*ip_rt_gc_min_interval which
 is a constant and get "dst cache overflow".

 Increasing  rhash_entries is the easieast way to attack this.. Give this
 a try. Monitor with rtstat. You might even have to quadruple your size.
