I don't think that is the reason at all. There are some forums with equivalent load but they're very fast.

Hello, Rocknroll!

I don't know your skills on managing the server, so sorry if I'm writing things that are plain obvious to you :), I am a sysadmin too, so here are some basic tips for slowness, it's not a bad thing to double check them.

Is php caching installed and working well? (On the forum settings' side if it supports it, and also on the server by installing some php caching module, such as APC, or memcached.) Turning the cache on can make a HUGE difference in everything.

The site also has a huge database I guess. I worked with very large databases in the past, and my experience showed that after a reinstall/merge, sometimes the DB server software checks and verifies the whole database for errors, and on large DBs it can take a VERY long time, especially if the server's other resources are also exhausted.
Check if it isn't the database subsystem that takes heavy resources currently.

If you already past these things then consider this post meaningless and accept my apology... I had good intentions with the composition of it. :)

Thanks. All of that is good suggestions and I do welcome them. I am not a big expert but I've learned a lot during the years this site has been up. And yes all those things are a check. It is simply ddos issue. Site is working smooth and fast when there is only valid visitors on our site. But that is rarely the case lately I am afraid.

Well I've turned off forums for guests but it didn't actually make much difference. Those aren't real people opening the website via browser. It is just bots that hit the server with traffic and still get logged as guests with vbulletin. So I think I'll turn back guests viewing soon.

okay fair enuff but if its going to be an issue
and IF its easy enuff to do so then turn it off again
no point to allow somthing like this issue to keep the forum down and offline .

Shoutbox open please ;)
WE Shall see about a chatbox in due time if that can be possible ..meanwhile its more important to have forum open above all else forum running online is a far greater concern to every member:thum:

Like old saying goes ..all good things come to those that wait patiently :cool: :)

Hello!

Maybe it would be a good thing to check the serverlogs for patterns. If they are really bots, they may have a pattern in their queries. If you can find such a thing, you can block them on the server level: let's deny access to every visitor who uses that pattern... and do it in the webserver's config level, before they even reach the resource-hog PHP subsystem.

You can do the same with user clients. It's a long shot, but it's possible that the bots aren't identifying themselves as standard web browsers... in that way, they can be easily blocked by client.

This is interesting however, because AFAIK this is a neutral sat forum, with no intentions to harm anyone. Why would anyone attempt to DDOS it is beyond my knowledge :S
