Hello, 
  I have recently noticed  slower responces when accessing 
a NFS exported directory from a jailed environment  than 
a non-jailed one on the same NFS client ( FreeBSD 4.10-RELEASE ) .
The NFS server is Solaris 8 with a VxFS exported filesystem .
There are a lot of records in /var/log/messages on the client
about ``nfs send error 22 ...'' ( EINVAIL ) .

Jul  4 20:18:13 mail /kernel: nfs send error 22 for server
nfs-server:/global/v2c1
Jul  4 20:18:44 mail last message repeated 342 times
Jul  4 20:19:46 mail last message repeated 1242 times

The following command ``/usr/bin/time -h find Maildir -type f ''
takes  ~20min ( 20m14.71s real, 0.17s user, 3.11s sys ) in a jail 
and ~13s ( 12.45s real, 0.07s user, 3.58s sys )
in non-jail for the same directory ( 23881 files ) .

Times for the ``df'' command are ( jail -  1.00 real,0.00 user,0.00
sys) and ( non-jail - 0.00 real, 0.00 user, 0.00 sys )

Please, can anybody advise why there is such difference in times ?
