[plug] Off topic - couple of things.

[Lindsay Allen]

1.  I'm looking for a single voltage Pentium or clone.  P75-P133.

2.  Would someone review my squid stats, please?  It serves a school which
is connected by three 56K modems and eql.  I'm interested in tuning squid
to be as optimum as possible.  Here is the data:-

The box is the school gateway and does 
  minor web serving
  minor mail serving
  squid caching


Hardware:

P133 with 128 Mb and four modems. 
1.2G scsi for Linux
2.0G scsi for squid cache


squid.conf settings:

neighbor_timeout 5
cache_mem  24
cache_swap 1850
dns_children 8
#reference_age 1 year
quick_abort   20      50      40
#memory_pools on
