Now faster with Gzip compression!
Just following along at home with the Pair hosting doc page:
Using mod_deflate for Page Compression
https://www.pair.com/support/kb/using-mod_deflate-for-page-compression/
by just adding this to the .htaccess
AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml text/css application/x-javascript application/javascript
And this site was already plenty fast since it's straight HTML files composed using Publii.
