AFAIK, Linux has always had NFS in the kernel. However, as of 2.0.x, it's *really* slow (from my own experience using a RedHat 5.1 client connecting to a FreeBSD 3.0-current server over 100BaseT). The only real improvement I've found is to upgrade to the 2.1.x development kernels. They have *much* better NFS performance, especially for writes. I'm sorry I don't have exact numbers, but I was seeing differences of up to 100x when writing 10MB files over 100BaseT from Linux to FreeBSD! Since you're using RedHat 5.1, you should already have recent enough versions of the system utilities to make a jump to the 2.1 kernel fairly straightforward, but read the directions at http://www.linuxhq.com/ for more information before you start. With LILO, it's pretty easy to keep your old 2.0.34 kernel around in case something goes wrong with the new kernel. Also, it's a good idea to make an emergency boot disk with mkbootdisk before you upgrade in case LILO gets hosed. Good luck!
