Just looking for seat-of-the-pants estimates. How's the board been performing these last 2 days, compared with the week prior?

Once I get a couple of answers I'll chime in again.

[Mal H]

I voted "yep" as there does seem to be an improvement. However, for the past couple of hours I've been getting "DNS lookup" errors for THR only.

[Edit]
Nevermind - I just saw the explanation in the "APS down?" thread.

[Derek Zeanah]

Re: DNS lookup.

Try it now. Better?

We've still got one nameserver trying to answer for two, and I remedy that until I'm told for sure that the fix won't knock another machine offline, but I recreated THR's zone so we should be good.

Though to be honest I don't really understand where the problem originated. Thought my zone files were still fine...

[pbhome71]

Well Derek, it does not seems to be any faster for me.

You can check my IP. I'm coming in from California. :)

I did have some domain name resolving issue a couple of times today, though.

Do you use DNS loadbalancing?

Everything was cooking along great all day until 0430-0440 and things went all freaky.

Voted yup,

Seems ok 0946 EST Friday 3/30.

APS down though?

Do you guys put the server down for maintenance regularly?

I'll come back here and tell you if things seem finicky later.

[280PLUS]

Ok, same day 0959 APS back up on both addresses and both APS and THR seem to be racing right along for me.

[Derek Zeanah]

Yeah, it looks like we've been messing with a couple of problems: APS is unavailable to some due to a DNS issue I have no control over (see the other thread in this section). It should be up and running fine for those that can get to it, or those that use the other method to get there.

THR went slow because of an "upgrade" that ended up really slowing things down. I patched it as best I could, then decided to downgrade again. Still saw some weird slowness issues though.

I'm at the point where I'm no longer looking for a link with the timing there -- looks like things are just busy enough that sometimes THR runs out of available memory and goes to swap, and things go unresponsive for a few minutes. This seems to be linked to searching as it's one of the things that require the most resources.

So I turned off searches for anyone not logged in, which reduced the load a bit. The fix will end up being new memory though -- might get to that next weekend (need to see how things work out).

[280PLUS]

Yea, I've learned to fear the word "upgrade"... :eek:

:D

[chakup]

'm now looking for the post on why it's been down. when I can get in it's running great, but 1/2 the time I can't even get on the site.

[Nitrogen]

seems like less "hang time" between searching for new posts, or posting.

I used to sometimes see about a 15-30 second wait during certain times, buit not yesterday.

[280PLUS]

Just FYI sunday 4/2/06 2104 EST (DST) (whatever) APSis acting up. Repeated "cannot find server" would not go into edit. I'll go back and try again...

:D

Went back and it works fine now only a few minutes later. Couldn't get it to open for a while there. Seems ok now.

Hi Derek,
During my years in IT, we spelled "upgrades" as: N I G H T M A R E S.

Overall THR is running pretty good this evening but about 5 minutes ago I had one timeout after clicking on "Post Reply". Seems to be working OK now.

Good shooting and be safe.

[Atticus]

Seems to be working better.

[waterhouse]

It's gotten much better for me. Still not where it was a couple weeks ago, but the delays are much less frequent now than they were last week.

[280PLUS]

~ 0540 EST 4/4 had time out issues with both THR and APS together. Back in THR now at 0544...

Going for APS to see how it is there...

[cosine]

This place has been slow all day. Noon, 3:30 pm, and 9 pm were the worst times. (CST adjusted for DST) In fact, I even got a couple of IE "can't find the page" or "can't complete your request" pages a few times.

[JohnKSa]

Today is the worst I've seen in awhile...

I can't really tell if it's just plain slow, or if we're having long and frequent stalls. Leaning toward the latter.

[Mal H]

Ditto - it hit the doldrums in the early evening. Nothing was moving.

[Car Knocker]

As noted, not a good day today.

[Derek Zeanah]

Am out of town. Will try to keep an eye on it.

[tyme]

JohnKSa, roughly, searching takes forever, which causes stalls, and every once in a while one of those stalls will get bad enough that mysql hits swap. When that happens, it's all over for a while.

vbulletin was not designed with scalability in mind. There is a simple way to fix searches or at least speed them up significantly, but it requires hacking up and rearranging some of the search code.

That people have been kvetching (I suspect the b* word is forbidden, but that's the sentiment) about vbulletin's scalability for years, while jelsoft has done nothing significant about the primary problem, speaks volumes about their lack of competence.

[LHB1]

Derek,
Just had another s..l..o..w response and timeout when trying to post a reply. Interesting thing is that my post is usually there when I exit/return even though I get an error message saying that website is not responding.

Good shooting and be safe.

[JohnKSa]

tyme,

Oddly enough, I find the search feature to respond very quickly. When the board is stalling, it's simply opening threads or sub-forums that will take forever or time out.

I figure that the searches use a lot of resources, but find it strange that they always seem very responsive while the simpler things like opening threads or posting replies seems to be the sticking point at times. Seems like the board software gives priority to the search feature even if it's at the expense of the other functions.

Is there a way to reduce the priority level of the search functions so that they don't bog the rest of the board down?

[tyme]

Yeah, I wasn't clear. Reasonable searches don't cause problems. The slowdowns are caused by searches for common words.

[GoRon]

Been kinda slow and clunky for me all weekend.

[BamBam-31]

I find that I can only get on THR around 2:00-4:00am. During more normal hours of operation, I get the "Can't display page" message every single time. This has been going on for weeks, and it's really affecting my sanity. Other members I know personally do not have the problems I have logging on. Dunno what's going on....

:(

I had a few timeouts last night, 4/11/06, around 11:00 PM eastern
