Re: [tor-relays] max / burst speed

["Steve Snyder" <swsnyder@xxxxxxxxxxxxx>]

I run 2 middle nodes, one at 150KB/300KB and the other at 100KB/200KB.  Both running what ever is the latest stable version of Tor (0.2.2.33 at this writing).

The 150KB/300KB node (Linux i686) occasionally spikes to the specified 150KB/sec, but 40% - 50% utilization is more typical.

The 100KB/200KB node (Win7 x86_64) never gets to the specified 100KB/sec of traffic.

Either there is simply not enough traffic to saturate all available middle nodes or Tor's node selection algorithm is, um, sub-optimal.

Also, I have come to distrust TorStatus.  Why?  Because difference sites will have different numbers while supposedly monitoring the same network.  One of my nodes is currently showing an Observed bandwidth of 10KB (yes, ten) at torstatus.blutmagie.de while the same node is showing an Observed 83KB at torstatus.all.de.  Don't take the reported values as gospel.

I can't speak for others, those with large amounts of BW usage or even
those with lower BW usage, but I know I never in the past 2 years have
never come close to using my available bandwidth.

I maybe wrong in this assumption, but I am thinking , at least now,
that there are certain nodes that dont get a large amount of traffic
like they used to, that the BW is more distributed among those nodes
that are available.

Hopefully someone will jump in and clarify this better.
