installed mod_deflate but no improvement

Question

I have installed the mod_deflate on centos. In virtual host file I have added the following

  SetOutputFilter DEFLATE
  SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$  no-gzip dont-vary
  SetEnvIfNoCase Request_URI  \.(?:exe|t?gz|zip|bz2|sit|rar)$ no-gzip dont-vary
  SetEnvIfNoCase Request_URI \.pdf$ no-gzip dont-vary

  DeflateFilterNote Input input_info
  DeflateFilterNote Output output_info
  DeflateFilterNote Ratio ratio_info
  LogFormat '"%r" %{output_info}n/%{input_info}n (%{ratio_info}n%%)' deflate
  CustomLog /var/log/httpd/deflate_log deflate

its show the compression in log also but not showing improvement in pageloading time.

Please guide for the same.
