Comment (by Vort):

 I will test this once my test relay will be in consensus.

 But now I can say that I see lags on select() calls.
 In normal case, select() returns 1 after send() with 10035 code almost
 instantly (within 0-1 ms).
 In slow case, select() is running for 10-100ms, often returning 0 because
 of timeout.
