Sure.

Before:

[ ID] Interval       Transfer     Bandwidth
[  1] 0.00-60.02 sec  5.16 GBytes   738 Mbits/sec

After:

[ ID] Interval       Transfer     Bandwidth
[  1] 0.00-60.01 sec  4.87 GBytes   697 Mbits/sec

I was surprised as well. These numbers seem to be within the margin of error.

I tested 'After' again just now:

  - - - - - - - - - - - - - - - - - - - - - - - -
  [ ID] Interval           Transfer     Bitrate         Retr
  [  5]   0.00-60.06  sec  5.15 GBytes   737 Mbits/sec  963             sender
  [  5]   0.00-60.06  sec  5.15 GBytes   737 Mbits/sec                  receiver

  iperf Done.

I can spin up another couple of unmodified VMs if you like - they'll be 
created from older stable/14 snapshots - and compare against those.
