[Rhm-users] RHM performance

[Andy Grove]

Hi Alan,

I'm away for a few days on business but I'm pretty sure I was using 1024 byte messages for these.tests.

I think it would be useful if I made the source available when I get back to the UK at the end of the week.

Thanks,

Andy.

I reread your message and I see you already told me the machine specs. 
Can you tell me what size of message you used?
