What slows a site down?

[SPEEDKILLZ]

I have noticed my site has gotten slower over the last few days. I contacted my host and they said they installed something which should boost performance. Then told me it could be on my end. I am on a private server which should be pretty quick, so i am wondering what sloes a site down?

Could be too many bots hitting it at the same time. There are a lot of bad ones out there

I would think on a private server it still shouldn't be that slow? Usually just shows around 30-40 users? Is there a way to speed it up? Mod, addon ect...

Private server? Do you mean dedicated, not shared?

If you are on a dedicated server, you most likely will have the ability to access the server logs. Take a look a peak times and then examine the logs at that point. It is useful to grab a log analyzer to parse through the data.

Do you have root access? Are you on a VPS or shared?

Your host's call center agents - their first and only job is to blame YOU. Keep that in mind.

You have many problems Mods won't address. You can learn ALOT from the webpagetest dot org site.
