compile drivers as module or built-in problem

i compiled Linux kernel with all drivers as built-in (all network drivers also compiled as built-in). all things work but ping time goes 开发者_如何转开发irregular (10ms , 90ms, ...). is it from built-in mode in compilation or problem is from another thing?

It shouldn't change a thing. Irregular timeouts usually come from either faulty drivers (but whether you have them built-in or loaded dynamically shouldn't change anything) or faulty network.
