Hi, I have enabled gzip compression following the wiki instructions like this:

location / {
#....

gzip on;
gzip_min_length 1000;
gzip_proxied expired no-cache no-store private auth;
gzip_types text/plain application/xml text/javascript text/css application/x-javascript;
gzip_disable "MSIE [1-6]\.";

#...
}

unfortunately, both Yahoo's yslow and Google's pagespeed tell me that I should enable compression for better performance.

How can I find out why compression doesn't seem to happen? I've selected the mime-types after having looked at them in chrome's web inspector.

Thank you in advance,
Jakob.
