When using the default NFS export options (in=20 particular sync), I see NFS write performance of ~50k with the 2.4.18-5=20 kernels. When set async, performance comes back up to par. I can give y= ou=20 the bugzilla # I reported it under, if you like. -- Rex ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ NFS maillist - NFS@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nfs
