Comment (by cypherpunks):

 > Try to replace code

 Idea behind this: small socket buffer (SO_SNDBUF) and openssl internals
 returning TOR_TLS_WANTREAD for already blocked on read socket (bw limits)
 leads to lag (100ms by default) for writing, so your relays write less
 bytes.

 You could also test this theory without patches by decreasing
 TokenBucketRefillInterval value (will lead to more cpu load)
