Talk:VPS performance

This article kinda sucks at the moment, but I think the subject has potential. I was just trying to gather some research from the forums together. I asked Dreamhost for some more info on the topic of VPS performance, and will post that when it becomes available. Nathan Larson (talk) 00:54, 3 February 2014 (PST)

What would be an example of complex applications? Thanks.

I think I have some very good information for you to take a look at, and maybe it will help clear up some of these questions you have regarding our VPS service:

Unfortunately I can't give you exact specifics when it comes to CPU speed but honestly what it comes down to is how much of a load you're expecting as to if this is going to be a good service for you. Most sites are perfectly fine on shared, but if you are are expecting or having a lot of growth then it might be something that's good for you. I honestly can't say for sure if your site(s) would be a good candidate for that.

As for your other question, on shared people can affect the other customers on our Shared service--as unfortunate as that is it does happen from time to time. Those that are consistently going over their allotment (of RAM for example) have their processes killed. So it shouldn't be something that happens often but it is something we watch try to watch for.

An for an example of a complicated application, that would be something like running background processes that are listening IE: servers.

I hope I've managed to answer your questions, but if I'm missed one or you come up with any more, feel free to reply to this email to re-open a support ticket with us.

Have a great day!
