[PVFS-users] version 1.6.2 slower than 1.60?

[Jeremy Enos]

Nothing else changed on the system.  I've put 1.6.0 back on again and 
verified an improvement.  I use the same configure options for each 
one.  Snipped from my spec file:

%install
# Make and install PVFS
cd $RPM_BUILD_DIR/%{name}-%{version}
./configure --prefix=%{buildroot}/%{prefix} --enable-lfs

# Make and install PVFS kernel module
./configure --prefix=%{buildroot}/%{prefix} \
   --with-pvfs=%{buildroot}/%{prefix} \
   --with-moddir=%{buildroot}/lib/modules/%{kernel}/kernel/fs/pvfs \
   --with-kernel-headers=%{kernel_source}/include \
   --with-newstyle \
   --sbindir=%{buildroot}/%{prefix}/sbin \

Let me know if you need anything else.  Thx-

         Jeremy
