Re: Low Cost 10G Router

Well, the cores on a many-core CPU aren't going to have the "torque" that a Xeon would. They're also still working on 
the software. It has gotten a ton better over the life of the CCRs thus far. BGP is still atrocious on the CCRs, but 
that's because the route update process isn't multithreaded. It won't be multithreaded in the next major version 
either, but they will have done some programming voodoo (all programming is voodoo to me) to reign in the poor 
performance issues with full tables.

So this new $1295 Mikrotik CCR1036-8G-2S+EM has a 36 core Tilera CPU with 
16GB of ram. Each core is running at 1.2Ghz? I assume that Mikrotik is 
multicore in software, so why does this box not outperform these intel 
boxes that everyone is recommending? Is it just a limitation of ports?
