If the feature was written as:
-For every thread page of 20 posts that someone views:
 -for every user that posted:
  -look through every other user's ignore list and add up the times that user has been ignored

That's basically how it works because the ignore mod (which I didn't write) stupidly stores ignore info in a single column per user like "35,3,...". So each ignore button needs to scan through all established users. The cost of this used to be very little, but it has increased substantially as the number of users has increased. I added a lot of caching long ago to offset this, but the cost is too high now even for that. I need to mostly rewrite the ignore mod so it stores data more sanely. No too difficult, but it requires a somewhat large uninterrupted block of time, which I don't have right now.

Coloring the word "ignore" with a darker color when a user is ignored by many people.
I dont see how such a small error can make such a big difference.

it certainly could cause server load. If it comes back, it would probably not be a "live" statistic, but one that is compiled nightly per-user.

That totally makes sense. Why add this feature if it was soooo resource intensive?
I don't think it was actually that bad back in 2012 (resource wise) but as the forum has grown such a huge amount since then it's just been getting slower and slower, have a look through the stats on here https://bitcointalk.org/index.php?action=stats

Didint even know this page existed. 65.1 million views last month!!!

I guess it had something to do with this:
I've had to totally disable this feature. I will fix it in a few days.

Seems to be running a lot better right now either way.  Smiley

What is "THIS FEATURE"?
FYI: Clicking a quote title will take you to the appropriate thread where the post was quoted from (quotes can be edited so this may not always run true)

Ahhhh, that helps a lot. Thanks.

I was getting it with a 50% frequency a few days ago. I am still getting it today, but not as much as before.

This is what happened when they were attacked before, not much we can do on our end since it's just a forum, I'm getting it too.

Gar. 502 error ate my top post, and it took five minutes to navigate here to complain. Another DDoS?

Yes it is. Every other page gives me a 502. I guess if we wait it will go away.

Forum is growing rapidly with 31,775 new members in December and 65,132,393 page views per month so depends if admin is investing in HW upgrade to cope, seems not.

I would think there must be a way to cache some of the content to cope better with all the page refreshes everyone does.

You lead and I'll watch you walk away.
See this fellow a lot today.

502 Bad Gateway


In fact, as I posted that post I saw it.
So meta.

Maybe 502 Bad Gateway is the new name of the forum. Is there a new coin called "Bad Gateway"?
