[rds-devel] [ofa-general] InfiniBand/iWARP/RDMA merge plans for 2.6.26 (what'sin infiniband.git)

[Scott Weitzenkamp (sweitzen)]

Rich,

On Nov 1, 2007, you wrote this to rds-devel:

  "Netperf is too simplistic in that all it seems to do is stream data
in a 
  simple loop. This is not how Oracle uses the IPC and again does not 
  reflect what it would take to make UDP reliable.

  For this reason we are not interested in having Netperf support RDS
and 
  or seeing Netperf data."

I would like to see RDS supported by existing common tools like netperf,
iperf, etc. so we can easily compare how RDS performs to UDP for IPC
models other than Oracle.
