 * hi everyone,
 * we are currently having some serious performance issues with our multisite configuration.
   Since early Monday morning we are getting a constant 300 to 500 visitors (20,000
   visitors / 100,000 page impressions since 11am) on one of our sites and our dedicated
   server is taking a serious performance hit.
 * We could already narrow the issue down to Wordfence, since disabling the plugin
   immediately resolves the issue. Disabling live traffic analysis somewhat improved
   the situation but wait times are still too long.
 * We haven’t had any troubles with Wordfence and this type of traffic in the past,
   so this came as quite a surprise.

 * Live traffic does add some overhead, especially if you have a browser open to
   the page. I’m not sure you would be hit that hard with that number of visitors.
   Can you check your options page and screenshot the firewall rules and post them
   here or let me know if you want to email instead. Also, can you see what urls
   they are hitting?
 * Thanks!
