Hi, I wonder where can I find documentation or information on how Linux's zerocopy works. Specifically on what conditions does data copy get eliminated? Also does it speed up all read and write operations on sockets? Or it just works for certain drivers or network interface cards? I went through the kernel source code and still see copy_from_user() calls in the data paths for socket writes. But I am new to the kernel source. Thanks for any information. __________________________________________________ Do You Yahoo!? Yahoo!
