very interesting
the provided xps project from xapp941 results 230Mbits but your custome sys=
tem is 83.0Mbits, yes?
just, are you sure the ppc core has the same core clock frequency in both d=
esigns? I mean may be the xapp941 is running at 300MHz but yours at 100MHz.=
=20
And what about a custom system with 9.1SP2? does that gives the same perfor=
mance?
Finally If possible please release the test results for TCP streams. ( 9.1 =
no SP and 9.1 SP2 )
thanks

yes

both run at 300MHz
And what about a custom system with 9.1SP2? does that gives the same performance?
haven't tried this yet
Finally If possible please release the test results for TCP streams. ( 9.1 no SP and 9.1 SP2 )
