This is strange thing.

All mods have some kind of impact, the biggest impact single mod had on my site was DBTechs Advanced Post Thanks and Like prior version 3.2.5, when they optimized it enough so I can use it again on my site.

I'm telling this as I'm using vBSEO at the moment (still), but over time I'll transfer to DBSEO. So big difference in server load means that either your server already was "on the edge" (server load isn't linear) and DBSEO just crossed it, which means you should have stronger server, or something should be better configured, or something in code optimized.

Whatever is, consult with DBTech before you turn off DBSEO, they'll help you, and probably even solve it.

A important fact most don't realize.

We generally can't answer Pro support queries, but as this goes for both Lite and Pro I can answer:

Have you added an opcode cacher other than Filecache to your config.php file? If you install XCache or APC and configure vB to utilise it, DBSEO will also be able to utilise it to reduce server load.

In a perfect world, there would be such a thing as a standardisation table for resource consumption vs. hardware, and the server load figures would be replaced with a more comparable performance metric.

What a Single-CPU Core 2 would think is server load 15 probably would be 0.15 on our Dual-CPU Ivy Bridge server, etc.

Well, they say that 1 (talking about server load as linux shows it) means 100% server load of one CPU core.

On 4 core CPU having server load of 2 would mean 50% server load for that server. 4 would mean 100% server load for that server. But, even with 6 on my 4 core server (which means 150% server load), my users probably wouldn't notice anything wrong. After 8 (200% server load) things starts to be noticeable to outside world.

Bigger problem is, what's causing this server load, is it some kind of unusual event, or something normal. If it is something normal, it's time for new server, or time to discard some of the mods if we talk about vBulletin based sites.

help?

spiders_dbtech_dbseo.xml - is one of the files that is suppose to be uploaded. Currently it cannot be located, check to make sure it was uploaded and uploaded to the right location.

charged hundreds of times but the file does not appear, only appears vbulletin

because the "stopwords" are not removed from the link BUT only in part of link for the "title" of the post (not categories and sections)

I had this same issue and found that for some reason Filezilla was not allowing upload of this file. I uploaded the file manually thru the file manager in the host and all was good.
