We can not answer such a question without getting more details. First of all, do you experience any performance related issues using your server? We don't know how much memory your server has and we don't know how many processes are executing and so many other details.

I can see that your server is swapping which is generally not a good indication. To keep your server optimum, you need to avoid swapping as much as you can. This can be done by estimating the needed memory by your applications and upgrade memory when needed.
