Slowness
I've experiencing a lit of slowness since I've signed up.
Am I the only one?

Do you have any specific pages or times of day that this is happening in particular? Also, where are you connecting from (geographically)?
I haven't noticed any slowness personally, but we can try and see what might be causing it for you.

Hi Kyle,
I'm located in Houston, TX. When I do updates to my documents or refresh the
dashboard, it hangs for about 4 seconds. Not always. I would say 40% of the
time.
Thanks.

I'm seeing something too, but it's very random and not database related. I'm looking into it.

Rick,
We've been having the intermittent slowness issue since last week. Gets pretty slow at times, taking over 2 minutes to load a ticket.

Any word on this?
It's gotten better but still having the occasional slow down.

Noticing this from my location, as well. Tickets are slow to load, assets slow to process...

We're looking into this, but it's very random. Traces show that most of the time it's fast, and a few requests here and there are real slow. We're having issues pinpointing the actual cause of the slowness. For instance, NewRelic reports it happening in outside of the database during view rendering. That's a little strange, it's sounding like a hardware issue.
Mike: it sounds like you're talking about job queue slowness. That could happen if there are a flood of new jobs to handle. I keep an eye on the queue and it's usually empty.

Wow, sorry about the delay -- we've been going back and forth with our host on this. Application traces didn't point to anything code-related. I pushed out a few tweaks (queueing sphinx index updates in DJ, memcaching some stuff, etc) and none of it seemed to fix the issue.
Last night, one of the Engine Yard techs found that we have an extra DJ job runner on a server, causing it to swap. We think stuff should be a lot smoother now.

Thanks for the update, Rick. I don't recall seeing any slow issues yet today, good sign.

Thanks. Will keep an eye.

Hey guys,
This was getting progressively worse for a couple weeks, and completely stopped working for about 20 minutes just recently.
I saw your blog post that there was also a big issue overnight http://hoth.entp.com/2009/10/23/tender-slowdown but this has apparently not yet been fixed?

Same problems, different cause. The problems aren't as severe as last night's. We're just seeing increased activity. We're looking at completely offloading the email processing from the front-end app servers in the short term and upgrading the hardware.

We have been experiencing agonizing slowness for about a week or so, and it's happening right now. Pages take 60 to 90 seconds to resolve. When they don't resolve, they don't time out -- instead we get an error notice from Tender. It's not just our app (help.allaccess.com), but help.tenderapp.com as well.
FYI, It's 3:45 PM PST.

Hey wbenedetto,
It's a systemwide issue where we're being hit with heavy response times -- http://hoth.entp.com/2009/10/26/tender-status
We're still working to resolve the issue and sincerely apologize about the inconvenience. We hope to have everything smoothed out as soon as possible.

FYI, I just checked, 80% of requests to your tender are within 440ms. There
are a small number of requests that take longer.
@@@
Percentage of the requests served within a certain time (ms)
50% 167
66% 194
75% 216
80% 440
90% 2535
