I just experienced one of those 20+ second loads

Local time 2145 UTC-5, server time is 0248 -

Which brings to mind that server time is again slipping.

NOW - I'm thinking it was a function of our later-in-the-day server problem.

ah well - thinking is a good exercise -

Appeared to be a bit slow today, cleared cookies etc. Released / renewed IP, flushed DNS

Maybe worth watching  Smiley

What I did notice with my large site was that if Linux released the cache back to the kernel (which it can for a variety of reasons), page loads can be dog slow for a while, as the cache rebuilds.

Added to the fact something else was after memory (hence kernel requested the cache ram back), it sent IOWait through the roof...  ...I used to get occasional Linux crashes at this point, as YaBB processes start to back up, each needing RAM, making the situation exponentially worse, until all RAM and swap is gone.

Admittedly I had a couple of hundred thousand files in Messages, and a good 50,000 in Members - thats a lot to ask any OS to manage efficiently.

My working theory is that we are dealing with 'bot-swarms'.  Their registration attempts/CAPTCHA guessing leave many copies of YaBB.pl waiting to 'time out'.

Just a guess, and I don't have SSH access to dig around.

I think that's exactly what's going on. Our forum gets hit with 'bot-swarms' as well, but thankfully, our 2.4 version seems to run quite fast anyway.

At the present time we're getting around 500 error messages every 6-8 hours or so (we've set that number of entries before our error log rotates).

What pretty much always generates the errors are anti-spam measures. SpamFruits stops a lot of spam-bots, and so does ggn's anti-spam CAPTCHA hack. Actually, when I only used the latter, spam-bots were always stopped cold. It's just that I like how pretty SpamFruits look.

Hu-bots can easily defeat these anti-spam measures of course, but for some reason that very rarely ever happens (can't remember the last time we had a hu-bot). And now that we're back to using "Pre-registration with admin membership approval" again, hu-bots are unable to post anyway.

Now that I think about it aloud here ... I think after I post this, I'm going to go back to "Open registrations without approvals ... keeping my fingers crossed.

I should point out, too, that thanks to advice given in this forum about how to defeat another kind of spammer, I'm delighted to see the following error message (and similar ones like it):

Code
Select All
Your url contains words not allowed here! (ugg) 


Happily of course, legitimate registrations are still being processed without any problems (we use a very easy to read CAPTCHA).

I am wondering if the developers are ready to take Yabb to next level by introducing HTML5 soon? so we can see a precisely great forum application in the near future. Huh

Yabb's development is happening at Dandello's YaBB 2.5.4 Alpha (RC1) forum. I believe she may be working on introducing HTML5 at some point if it isn't already happening.

Our list is pretty good for the next iteration - HTML5, mobile support, UTF-8, starting to sorting things in preparation for an SQL version, the Admin Center... Grin
