knfsd -- Fedora nfs is slow

Hi, all,

  I got Fedora FC1 boxes running customized 2.4.25 vanlina kernel, But the nfs speed is way low.  I compared the dmesg output from original default kernel 2.4.22-1.2174.nptlsmp amd my new compiled kernel, and find the orignal default kernel reports:

	....
	Installing knfsd (copyright (C) 1996 okir@xxxxxxxxxxxx).

 But the newly customized vanlina 2.4.25 kernel doesn't report  the above line, is that the problem?  I definitely enable nfs v2/v3 support in 2.4.25 and it works with slow speed. 

 Thanks a lot.
