I have a dual 3GHz Xeon machine with a 2.4.21 kernel and thousands (15k+) of
ipip tunnel interfaces.  These are being used to tunnel traffic from remote
routers, over a private network, and handed off to a third party.

Is it possible to speed up creation of the interfaces?  Currently it takes
around 24 hours.  Is there are more efficient way to handle a very large
number of IP-IP tunnels?  Would upgrading to a 2.6 kernel be of use?
    

2.6 (and the associated 'ip' tool) does have some improvements for 
showing very
large numbers of interfaces.  I haven't tried more than a few thousand 
though...
