Not sure if this belongs in "third party" or "general troubleshooting"...
I have two expressionengine installs - one each in two different accounts, on one server fud, one on bitters. They are both at the same version level (1.6.4). Both have been running for years; both were updated to the most recent version a month ago (roughly). Other than posting entries to each, I have not done any system-level maintenance.
Within the last few days, one has started throwing page-render times of 150 - 250 seconds; the admin control panel renders in around 35-45 seconds. Long enough that the proxy at my work just gives up. Likewise my phone browser. The other site renders normally.
The render times on the slow one was so long I thought it had gone off-line. However I noted that a static html file loads quickly. I opened a help ticket and suggested it might be a MySQL or PHP problem. Support responded that they renamed my .htaccess file and the site loaded, so it was a coding problem on my end. I asked how an htaccess file that has worked for years could be the problem and if something had changed. They said nothing has changed and troubleshooting my code was out of scope. Of course it is - I agree.
As a side note, I notice no performance difference with or without the htaccess file. The site is so slow for me as to be effectively offline.
I've repaired and optimized all database tables (MySQL server grunt:mcadams).
I am asking here, what can I do to either troubleshoot an install that just fell over one day, or appropriately communicate the problem to support? I'm not sure how to politely and effectively respond to "it's your code - sucks to be you." I've been happily hosted here since 2002. I know a little, but not a lot. The problematic site is the members-only section of a dog club, but you should be able to at least load the "please log in" page:
For comparison, a similar but more normal site using the same EE version (but a different MySQL server):
Not sure how to proceed. Advice and suggestions welcome.
I'm in and out this weekend, so slow responses are not due to lack of appreciation! Thanks for any thoughts.
