Web应用程序的瓶颈？

Question

This question pertains to Ruby on Rails and PHP. When looking for a VPS host for a web application (haven't decided which of the 2 languages to write it in yet), what should I take into consideration more? Memory or CPU? I know that you need a fair balance of both, but which wall will I run into first?

I'm sure it depends on the type of work the application is doing, and in my case its the normal CRUD. My guess would be memory, but I'd just like to make sure.

Answer 1

I think the DBMS and the nature/number of the queries you will be making will be the most important consideration here, rather than anything pertaining to the language used. (Assuming the database is going on the same server)

Unless you've got a very small dataset, memory is likely to be limiting before CPU.

Also, you've not really specified what the combinations on offer are - so its hard to give an answer.
