XF 1.3 Massive Delay Between HTTP GET and HTTP 200 OK

Anyone else notice a big delay between the HTTP GET request and HTTP 200 ok when going to your xenForo site?

Oddly mine is that way for me at work and at home using chrome and firefox. Using developer tools Network Timeline, I have seen delays as long as 21 seconds.

What is interesting is if I use Chrome's incognito window - (under File Menu - New Incognito Window ... this does not use cookies)

- then my site loads like lightning.

What does this mean?

Mostly I am curious if others have experienced this and what you did to resolve it.

Thanks in advance,

sounds like a server issue since you're getting the delay from multiple locations. it could be anything from an unoptimized database config or caching issue, to a problem with an add-on slowing things down. enable debugging and see what queries are taking the longest. that might give you the best clue.

Yeah.. its been interesting to track this down... just became aware of this today, note the collisions:

Code:
#sh interfaces ethernet 0/1/33 | inc err
  0 input errors, 0 CRC, 0 frame, 0 ignored
  23150822561 packets output, 5058150841087 bytes, 0 underruns
  0 output errors, 373654557 collisions

sh interfaces ethernet 0/1/33 | inc err
  0 input errors, 0 CRC, 0 frame, 0 ignored
  23150822689 packets output, 5058150854214 bytes, 0 underruns
  0 output errors, 373654562 collisions
sh interfaces ethernet 0/1/33 | inc err
  0 input errors, 0 CRC, 0 frame, 0 ignored

Is the switch hard coded for the speed and duplex, or set to auto negotiate? That's a lot of collisions. What is the interface currently running at (both sides)?
