  The default (1024 fd´s) should be enough for 2000 users.
  Check cachemgr -> General Runtime Information on info regarding fd-usage
  and the nuber of spare fd´s.

  If you get lot´s of :

   Warning : Your cache is running out of file descriptors !

 in cache.log. Then you may need to increase them. Check the Squid FAQ
 on how todo this.

 ps: install and use the latest STABLE release.
