even viewing the ASP.NET MVC forum is horrific ....
crashes many times, totally random ... I think it must
be overloaded ... I had to try more than a half a dozen
times to post a brief new thread. Even "Preview"
had same behaviour. It's not scaling.

Could be all of http://forums.asp.net/ or just http://forums.asp.net/1146.aspx.

F.Y.I.

(probably entire forum ... *this* post just failed to post four times in a row)

Hi Gerry,

It looks like the forums hit a slow spot back then. I am not seeing this behavior anymore are you?

Re: evil behaviour today at http://forums.asp.net/1146.aspx

Hi Kevin,

yes, it finally has settled down for me too. Thankfully, because I've had
enough frustration with it this morning to last for months. For me,
it was not what I'd call a "slow spot"; it was more like being tortured.

Gerry,

Can you please let me know around what time you typically experience issues with posting or even browsing? Also, please include the timezone. Thanks!

Re: evil behaviour today at http://forums.asp.net/1146.aspx

Jay, thank you for asking.

Horrific behaviour can happen at anytime. Today, roughly from 10:00 for at least two hours,
possibly more. In my case, I'm in the Canada/U.S.A. Eastern Daylight Saving Time Zone.

It's not consistent to one time slot. Your best metric may be your server logs.

Today's behaviour had the smell one might expect if forums.asp.net was under a DOS attack.
Your router logs might be worth looking into also.

Generally, I'd call the behaviour random. Today's was the worst that I've experienced
since becoming a member of this community.

It seems that 10 AM EST is a sweet spot for bad performance. I started getting bad performance at exactly 10 AM EST today, and it is still going on 10 minutes a later. There seem to be other posts indicating the same problem around the same time, for example:

http://forums.asp.net/t/1389607.aspx

Is there some sort of batch job or scheduled task to run at this time?

Ditto @ 9 AM CST

>> Is there some sort of batch job or scheduled task to run at this time?

I wonder if the AM and PM got switched for the start time.

Re: evil behaviour today at http://forums.asp.net/1146.aspx

I see the odd patch of bad performance from this site. When it occurs I try to check performance of another US based site to try rule bad response by my ISP.

Currently about 50% of page loads on this site are timing out.

Just now, 12:17, Eastern Daylight Saving Time, from Reply to "Sign In" was 35+ seconds;
from "Sign In" to this message composition box, another 20+ seconds.

This needs to be addressed urgently, that's two days in a row.

Many members of the community may stop participating if this gets worse.

Please Jay ... we are all looking to your team to find and cure the cause.

At least one post has missed out on a reply from me because of the bad performance.

Hmmm... Day light savings time change playing foul somewhere?

Hi Kevin ... I'm doubting it's DST because HTTP traffic is not time zone dependant.

Nevertheless, interesting theory. Time may tell.

Scheduled tasks / batch jobs might be.

Re: evil behaviour today at http://forums.asp.net/1146.aspx

Hello, again, Kevin ... I've a "yes but" for your "might be".

Let "glob" represent a time and traffic intensive "scheduled task / batch job".

----+----5----+----6--glob---7----+----8----+----9----+----x----+---- pre DST

----+----6--glob---7----+----8----+----9----+----x----+---- DST (a)

----+----5----+----6--glob---7----+----8----+----9----+----x----+---- forgot to DST (b)

let's say the glob was scheduled for a certain time frame such as between 6 and 7

okay, so with DST, 6 o'clock happens an hour earlier, but it's still 6 o'clock;
depending where the forums.asp.net servers are, this still should not jump
to mid morning ... case (a), above

OTOH, say the servers where not switched over to DST, case (b); could happen,
but highly unlikely because Microsoft is likely using Windows servers that
have the new time zones setting themselves automatically (assuming
automatic updates are enabled); regardless, let's say this is the case,
the effect would appear to be a shift one hour ahead ... however, Eastern DST
is a time zone that Microsoft would not likely want to impact, so I doubt
that the shift would be into core Eastern DST mid morning hours.

That plus, we would all be saying that the ugly time has shifted
from 9_to_11 to 10_to_12. But it was not a shift per se, rather
it's a new behaviour that just happened to coincide with this year's
commencement of DST. Ergo, that's why I'm doubting anything
more than a coincidental connection to the commencement of DST.

Again getting timeouts or pages not displaying properly from about 10:00 to now 10:20.

Tried another US site and got a download speed of 280kb / sec.

Re: evil behaviour today at http://forums.asp.net/1146.aspx

Still getting pages from this site timing of displaying wrongly (e.g. avatar images are about double normal size and text size larger than normal), yet I could go to http://saturn.jpl.nasa.gov/mission/presentposition/ and the site displayed without fault.

Re: evil behaviour today at http://forums.asp.net/1146.aspx

I assume you mean GMT time in your case? Response here seems okay at the moment (08:20 Eastern DST).

Hope it stays decent too. I wonder whether anything has been fixed from an infrastruture point of view
or the problem has gone away for no apparent reason.

Re: evil behaviour today at http://forums.asp.net/1146.aspx

GMT and UTC are essentially the same.

Re: evil behaviour today at http://forums.asp.net/1146.aspx

:)) I feel your pain. I got some slowness in the morning today and once during the day, but now it seems to be OK.

Re: evil behaviour today at http://forums.asp.net/1146.aspx

I'm getting terrible performance as of 5:45 AM EST on 3/16 (30+ seconds between pages).
