GZIP-Komprimierung

das ist eigentlich nicht Sache eines Themas, sondern der Einstellung deines Providers.
Entweder den mal anschreiben oder via htaccess ( im Falle eines Apache Servers ) versuchen die Module zu aktivieren.
moddeflate ist die neuere komponente gzip ist aber auch mit drin. (Ausserdem auch einige Sicherheitseinstellungen.

Das hier sind so Standard einträge dich ich zusätzlich zu dem WordPress Einträgen noch mit in der htaccess Datei habe:

# secure htaccess-file
<files ~ "^.*\.([Hh][Tt][Aa])">
order allow,deny
deny from all
satisfy all
</files>

# Keep-Alive
<ifModule mod_headers.c>
   Header set Connection keep-alive
