You have the values wrong. Lower values get less traffic.

It's a simple ratio, providing for asymmetric load balancing. For
example, suppose you have three servers at your main site + one
offsite backup on a slow link. You would set them up like this:

server 1 1000
server 2 1000
server 3 1000
server 4 1

In this case, the offsite backup would get something like 1/3001 of
the traffic, while the other three split the other 3000/3001 evenly.

A value of 0 will be treated as if the server were unavailable, so
good values are between 1 and about 65000.
