Time to first byte (TTFB) high in Chrome & FF, instant in Safari

We have a Wordpress instance running on Ubuntu 12.04 LTS and Apache 2.2.22, and it takes > 3 minutes to load a page in Chrome and Firefox, whereas it loads instantly in Safari.

I have no idea what the issue could be. I tried setting

HostnameLookups Off

in Apache, in case DNS lookups of client IPs slowed everything down, but that didn't help.

Admins recently upgraded the Wordpress instance, but I have no idea if the issue is related to that.

Проведено обновление дистрибутива до 14.04.5 LTS. Это исправило его, таким образом, основная причина ошибки останется загадкой навсегда.
