Hello,

I will preface this by saying I am not sure if this issue is even related to K2. I would like to at least rule it out, if not fix it.

I have a testing version of the new company site at dutchmantreespade.com/zzdutchmantest live. It frequently suffers from a horrendously long (often 15 seconds plus) Time To First Byte (TTFB) when navigating to a new page. The files affected by the slow TTFB are usually the page document and jQuery or other javascript files, but it varies wildly.

I have seen no signs that it is an SQL issue: there is no sign of resource drain or length queries on the database. I have tried testing other joomla sites on the same host, and I have not encountered the issue at the same frequency (non-joomla sites and joomla test installations very rarely also suffer from long TTFB, but I am quite willing to write that off as being a host/ISP issue and not worry about it). The server has plenty of memory/CPU power to spare: despite the long wait, there is no sign of resource strain anywhere.

I have tried disabling every other plugin and this has no helped. I am currently running Jotcache to help with performance, but it has made no difference on the slow TTFB issue (and I was having the issue long before installing it). Disabling K2 completely breaks the site so it is the one thing I have not been able to definitively test. I have disabled the K2 components I am not using, but again this has not helped.

I know I am basically grasping at straws here, but if anyone has a suggestion to resolve this issue or at least confirm it is not caused by K2 I am desperate for answers. Anything and everything is appreciated!

I checked with my host, and it was indeed an issue on their end. It has been resolved.

Let this be a lesson: just because site issues are usually self-inflicted, doesn't mean that they are always your own fault.
