I’ve been experiencing higher response times and lower throughput in my server last weeks. I use NewRelic to monitor server’s performance so I found out that queries to
/xmlrpc.php were having a gigantic impact in site’s performance.
Googling about that issue I found this post by Hugo Dias about fixing the problem denying access in
.htaccess file. However my server doesn’t use apache but nginx so I couldn’t apply that snippet directly. Fortunately porting the snippet to nginx is not so hard with StackOverflow’s help.
