Re: eCos Performance/ eth0,eth1 Routing problem (number of hops!)


Indeed, it was cache enabling problem.

Here is the new numbers which are getting closer but still needs some work:

Linux: max 26,000 packets (60 bytes) per second (single burst) with no drops

eCos: max 23,500 packets (60 bytes) per second (single burst) with no drops

I DO HAVE A SETUP ISSUE which I need help. I want to route packet coming
in from IP address: 192.168.1.80 to eth0 (IP ROUTE) to eth1 and eth1 to
route to its destination ip: 192.168.2.80. As you see the purpose is to
test performance of my driver and eCos vs Linux by SmartBits. Here is an
snap-shot of my eCos route table:

The ip routing between eth0 and eth1 is NOT happening. I am starting to
think the number of "hops" is the issue. Here is initialization prints. Is
there any other issue you see. Thanks.
