Apache Benchmark test load with gzip compression

ab_gzip.sh

ab -c 10 -n 1000 -H "Accept-Encoding: gzip,deflate" http://www.example.com/

I use these settings on nginx and haven't had to specify gzip_http_version

##
# Gzip Settings
##

gzip on;
gzip_disable "msie6";

# when proxy if backend returned a gzip encoded for a client that would not support it
# makes sense if we want varnish to store compressed content
gunzip on;

# add the vary accept header
gzip_vary on;
gzip_proxied any;
