Anybody sees frequent 10 sec. page delivery delay?

[marty]

i'm having a very strange page delivery delay problem. much too often i have to wait around 10 secs to get a response from the server.

 

 

- the delay is always very tight around 10 secs - never 8 secs, never 12 secs (see pix)

 

- the delay happens sometimes every 10th page,  sometimes every 2nd page, no consistency 

 

- without the super delay, delivery is without problems, around 1 - 2 secs

 

- even delayed pages have always normal php build times between 0.3 - 0.9 secs 

 

- strange: while waiting the 10 seconds for a response, a parallel ping is returned 10 times without loss and very tight at 140ms

 

- after 10 sec the page will always be delivered - no waiting forever, no loss, no reset

 

- the delay is independent of the page size. the first attached pix shows a "10 second" logout which only sends a redirect but no data

 

- i didn't get static pages delayed, only php pages (zend framework), but again php build times are always normal. 

 

- happens with different browsers. first pic: opera. second: chrome

 

- i'm on wdc006 - requesting in europe.

 

- other internet access without any delay or problems

 

see pix below for two delay examples 

 

whats going on?

anybody else has  delayed pages?

While it's difficult to say what is going on without specific account details, I know the server you're on was having some performance issues over the past 3~ days which we've addressed and have fixed.

 

If you're still seeing these issues please submit a support ticket so we can diagnose this specific to your account. Thank you.

ok. thanx.

 

will submit a ticket.

 

currently collecting some performance data with http://www.webpagetest.org requesting from phoenix.

 

the problem is not a continental network delay.

 

and it's persistent. meaning for maybe 10% of php/mysql pages you have to wait 10 secs for a response from the server,  

 

the php build times for these delayed pages are totally normal in the 0.1 - 0. 8 seconds range
