From 670e711dd19510316ecaa1f30d78f16ba66492f6 Mon Sep 17 00:00:00 2001 From: peter Date: Sat, 17 Mar 2001 09:31:06 +0000 Subject: Use a generic implementation of the Fowler/Noll/Vo hash (FNV hash). Make the name cache hash as well as the nfsnode hash use it. As a special tweak, create an unsigned version of register_t. This allows us to use a special tweak for the 64 bit versions that significantly speeds up the i386 version (ie: int64 XOR int64 is slower than int64 XOR int32). The code layout is a little strange for the string function, but I was able to get between 5 to 10% improvement over the original version I started with. The layout affects gcc code generation choices and this way was fastest on x86 and alpha. Note that 'CPUTYPE=p3' etc makes a fair difference to this. It is around 45% faster with -march=pentiumpro on a p6 cpu. --- sys/nfsclient/nfsstats.h | 1 - 1 file changed, 1 deletion(-) (limited to 'sys/nfsclient/nfsstats.h') diff --git a/sys/nfsclient/nfsstats.h b/sys/nfsclient/nfsstats.h index 6423e5a..259ec20 100644 --- a/sys/nfsclient/nfsstats.h +++ b/sys/nfsclient/nfsstats.h @@ -633,7 +633,6 @@ int nfs_savenickauth __P((struct nfsmount *, struct ucred *, int, int nfs_adv __P((struct mbuf **, caddr_t *, int, int)); void nfs_nhinit __P((void)); void nfs_timer __P((void*)); -u_long nfs_hash __P((nfsfh_t *, int)); int nfsrv_dorec __P((struct nfssvc_sock *, struct nfsd *, struct nfsrv_descript **)); int nfsrv_getcache __P((struct nfsrv_descript *, struct nfssvc_sock *, -- cgit v1.1
