NIS makes tar slow!

[Christian Schwarz <schwarz@monet.m.isar.de>]

$ time tar xzf /tmp/bash_2.01.orig.tar.gz 
real    0m58.624s
user    0m3.190s
sys     0m3.040s
$ rm -rf bash-2.01/
$ time tar xzf /tmp/bash_2.01.orig.tar.gz 
real    0m4.911s
user    0m2.510s
sys     0m1.450s
$

When running tar for the first time, I had these entries in
/etc/nsswitch.conf:
  passwd:         db files nis
  group:          db files nis
for the second time without the "nis" in both entries.

Does someone know if this is the normal? Any help is appreciated.

Here is my setup:

client host (where tar runs):
  "latest hamm"
  tar_1.12-2
  glibc_2.0.6-2
  base-files_1.3.5

server host (running NIS server):
  "Debian 1.3.1"
  nis_2.20-1

(Note, that the whole test has been done without NFS.)


Thanks,

Chris
