The past couple of weeks, we've gotten huge spikes on the server load around 11:00 AM Eastern time, without a corresponding increase in traffic. Its a difficult time to diagnose the problem, since I'm at work. I'll do some digging, and see what's up.

We seem to be getting a LOT of activity from IP addresses in Russia and The Ukraine during times when the server slows down.

Seems like the slowdown is not limited to that timeframe.Originally posted by Dan
People will miss that it once meant something to be Southern or Midwestern. It doesn't mean much now, except for the climate. The question, “Where are you from?” doesn't lead to anything odd or interesting. They live somewhere near a Gap store, and what else do you need to know? - Garrison Keillor
Looking into upgrading the server.

Tweaking current server settings during the day. Apologies in advance for inconsistent performance.

I have been having some issues for the past two weeks. Not sure if it is really between any specific hours. The search seems slow, and page refreshing is very slow.
Hmm.

^Me too. Seems like thread pages have been taking much longer to load
The thing that's weird about Cyburbia now is that we're getting a heavier load on the server, but it doesn't seem to be coming with a corresponding increase in the number of users on the site at any given time. Only a small amount of the increase in server load can be attributed to vBulletin 4. The server started slowing down about four weeks ago, and there wasn't a corresponding bump in traffic that could account for it. I also wasn't able to find any evidence of denial-of-service attacks. The only thing I can think of is that there's a extremely busy site that is now sharing the same VPS node as Cyburbia.
I've been tweaking the server configuration, but it's a short-term solution. It's a balancing act.
Anyhow, I'm probably going to upgrade to a new server at the same host. There shouldn't be a huge increase in cost on my end, but there might be a weekend when the site is changing IP addresses, and folks will get lost.

Trying some settings that should work for the short term. I'm doing a bit of smoke testing.

Okay, got the new server. Same host/data center, based out of Lansing, Michgan. I'll probably migrate either during the night sometime next week, or next weekend.

Still on the old server, but in the meantime, before we migrate the site, I'm trying some server configuration settings that seem to have helped somewhat. Things won't be blazing fast during peak hours, but it's better than before.
The slowdowns don't seem to be related to Cyburbia, but rather some other site on the node. At least this gives us a good opportunity to upgrade.

Not sure if this is related but occasionally it takes 30+ minutes for new posts to show up in threads. Like I can see the thread was bumped and who did it but I can't actually read the post. What's weird is it will do it for some posts but not others that were posted in other threads around the same time.
Didn't get around to the server migration this weekend. I'll try to get to it in the next few days.
