[openib-general] Architectural differences between new SDP and old

[Kevin Ball]

Hi Michael,

  I'm investigating some of the performance differences between the new
implementation of SDP and the old.  The profiles are substantially
different, with the new spending much more time polling than the old
did.  I'm not sure if this is a direct effect or secondary due to
something else.  Could you (or anyone else who has already looked at
this) give or point me to a high-level overview of the architectural
differences between the two implementations?  This would save a lot of
time.  Thanks!
