Deli,
Given:
Calibrating delay loop... 2.98 BogoMIPS
I'd suspect you've not enabled DCACHE/ICACHE....

Subject: [microblaze-uclinux] slow performance on XUP V2P
Hi,
I got a uClinux/MB up and running on the XUP V2P board. However, I feel the system is rather slow. The ping to the network interface is like,

which I think it should be less than 1ms.
Also, when I type "ls", it takes seconds to response. But the file system runs from RAM, how comes the delay?
I wondered if I made any mistake in the configuration or the uClinux/MB is normally such slow.
Cheers
Deli
