+2.28.  Why is extracting files via tar so slow?
+
+{AJ} Extracting of tar archives might be quite slow since tar has to look up
+userid and groupids and doesn't cache negative results.  If you have nis or
+nisplus in your /etc/nsswitch.conf for the passwd and/or group database,
+each file extractions needs a network connection.  There are two possible
+solutions:
+
+- do you really need NIS/NIS+ (some Linux distributions add by default
+  nis/nisplus even if it's not needed)?  If not, just remove the entries.
+
+- if you need NIS, use the Name Service Cache Daemon nscd.
