Desktop Remote Access

I want to ask do we can use windows dektop remote access to see my server on dreamhost to check RAM and CPU usage.

I am not sure that DreamHost uses Windows very much if at all.
If you have a PS you might be able to install vncserver? but really your best bet would be to (from a Windows computer) use Putty, SSH into your server, then run top.

If that is the first time you have heard those phrases it might sound like gobbledygook but it is really quite simple to do…
Download Putty:
run it
put in your domain and password
that should log you in
type in: top
hit enter
you should be seeing your CPU and RAM usage

NOTE:*it has been a couple of years since I have used Windows, so those instructions might be a rough guide.

Thank you that is what I get

15 GB of 16GB are used I do not know why, how I can trace which program use the memory.

Your server is shared with other DreamHost customers. Don’t worry about CPU or RAM usage — we’ll keep tabs on that.

Dreamhost support team mentioned the slow web browsing to my domain is due to high usage of memory.
