I want to remove the contents from Google index. Google index include my websites huge number of pages indexed in Google index about 5,000,000 Pages earlier but now left pages are 3,025,000.I have made the following things but the removal of pages are very slow pace.Robots.txt:User-agent: *Disallow: /.htaccess:rewriteengine onrewritecond %{HTTP_USER_AGENT} ^.*Googlebot/2.1.*$rewriterule .* - [F,L]The is the content returned to Googlebot when it try's to crawl the content:HTTP/1.1 410 GoneDate: Sat, 05 Jan 2013 12:39:23 GMTServer: Apache/2.2.23 (Unix) mod_ssl/2.2.23 OpenSSL/0.9.8e-fips-rhel5        mod_fastcgi/2.4.6 mod_jk/1.2.37 mod_auth_passthrough/2.1 mod_bwlimited/        1.4 FrontPage/5.0.2.2635 PHP/5.3.19Content-Length: 661Connection: closeContent-Type: text/html; charset=iso-8859-1I had also used the html meta tag noindex, no follow but no effect as:<meta name=googlebot content=noindex,nofollow>I had also submitted for website removal but the speed of removing of contents is very slow. In last 35 days the only few are pages are removed. My website is also removed from Google search index but Google Webmasters Tools - Health -> Index status still showing 3,025,000 page and If I re-submit the site they will show already indexed pages. How can I increase the speed to remove pages.
