I also see the delay is happening while trying to get data from userapi.com, though I don't know why it's pulling data from that site. The site did successfully load for me eventually, and there is reference to a userapi.com script in the source code, but I don't know if it's legitimate or not.
If you believe the site has been hacked, there are a few steps you should take. First, reset your passwords. Second, restore your files from a backup that existed before evidence of the hack appeared. Third, update all your plugins and consider removing some of them if they aren't giving you any value, haven't been updated in a long time, or you have other reason to believe they may be vulnerable to attack.
If you don't know how to recover your files, take a look at this article: http://x.co/jBdY - you can recover files from daily snapshots up to 30 days old. Note, however, that it's possible the malicious activity occurred a long time ago, prior to your knowledge of it. For that reason, you need to take extra measures to ensure your files are truly clean (see the advice in the previous response from esmi), not just that the site works after restoring the files.
