10/21   If I ssh into machine A and then ssh into machine B and then back
        into machine A, is that slower than if I ssh into machine A and
        stay there?
        \_ Yes, in theory but if your pipe from you to A is smaller than the
           pipe  A <-> B it may not matter much.  If you're only typing over
           this link it won't matter at all.  If you're sending data through
           an ssh tunnel then it could matter a lot.
           \_ What kind of answer is this? Don't answer questions you know
              nothing about. The correct answer is that your latency will
              be increased by double the amount of the latency of your A->B
              link but your bandwidth should not be effected.
              \_ The verb you're looking for is "affected."
                 \_ Unless your subject is psychology, you will seldom
                    use the word affect.
                    \_ wtf are you talking about?  "affected" is the correct
                       word here. "effect" is seldom used as a verb.
