 * Hi all,
 * Few days ago my web site’s loading speed dropped significantly, and I can’t find
   out any specific reason for this. The WordPress web site uses BoldGrid and ColorMag
   Pro theme. The hosting server works fine, the deactivation of plugins did not
   resolve the issue and the change of the theme did not help as well. I managed
   to win few seconds of loading time with optimizer plugins like Heartbeat Control
   and Outoptimize, but it does not seem to target the root of the problem. I also
   tried changing DNS with Cloudflare but it did not resolve the issue. The analysis
   indicates that the main delay is at the step of initial server response. It looks
   like I tried almost everything. Do you have any other ideas what to fix?
 * Thank you!
