I am hearing from my IT department that Googlebot is causing as massive slowdown/crash our site. We get 3.5 to 4 million pageviews a month and add 70-100 new articles on the website each day. We provide daily stock research and marke analysis, so its all high quality relevant content. Here are the crawl stats from WMT: http://imgur.com/dyIbf I have not worked with a lot of high volume high traffic sites before, but these crawl stats do not seem to be out of line. My team is getting pressure from the sysadmins to slow down the crawl rate, or block some or all of the site from GoogleBot. Do these crawl stats seem in line with sites? Would slowing down crawl rates have a big effect on rankings? Thanks
