Hi,
i have a question to that.
My performance of the compressor is VEEEEEEEEEEEEERY slow in the
backend. Sometimes it take upt to 3 seconds to get a javascript file
with status 200 OK according to firebug network modul.
why does it take so long? any way to improve the performance?

As described, compressor compresses only once, but delivers often.

Add this to your localconf.php and uncomment the required .htaccess rules.
$TYPO3_CONF_VARS['BE']['compressionLevel'] = '9';

This produces gzipped files.

Also you should send expires headers:
<FilesMatch "\.(js|css)(\.gzip)?$">
        <IfModule mod_expires.c>
                ExpiresActive on
                ExpiresDefault "access plus 1 month"
        </IfModule>

        # ETag
        FileETag MTime Size
        <IfModule mod_headers.c>
                FileETag none
                Header unset Last-Modified
        </IfModule>
</FilesMatch>

Kind regards
Steffen
