First of all: I've just read this thread (link) in a search of finding the answer.
My laptop specs are roughly: Some mobile good i7 roughly 3 years old, 4GB RAM, Win7 and 500GB HDD and NVidia Quatro 1000M I believe. So specs are pretty good I'd say.
However after using a few programs, yes I do use some, I got the following open:
- Netbeans ~800MB
- Firefox ~600MB
- Windows services totalling ~500MB
- Skype ~200MB
- Random processes ~200MB
So that gives me 2.3GB RAM, however the problem is that my system is continously (after it's up for some hours, 12+ usually) using 3,6 GB RAM and I believe it is swapping the RAM to the disk way too often resulting in a very slow laptop, especially once I come out of Hibernate for the coming 20 minutes. I do need to mention that I practically always Hibernate it, until it's so slow that I'm forced to reboot it, and then it'll go back to Hibernate again.
I got this laptop 3 years ago from university, it's a Lenovo Thinkpad W520. I'm planning to upgrade to an SSD and 8GB or 16GB of RAM, but the support is quite slow, so it can take a while. (Making the appointment is a hell already, because all people who messed something up with their laptop get favored in the line).
As I'm typing this the RAM went down to 2,9GB and something like "Turn on Symantic Endpoint Protection" showed, possibly a clue? Still being slow as hell though. Also it seems that it has especially a lot of issues searching for a file, I was for example doing Win+Paint and it is taking ages to load. The CPU usage itself is fine, btw, like 5% or 10% when idle/typing stuff like this.
Also I know obviously that I cannot expect the same speed as I have at my desktop with i7-3770, SSD and 16 GB RAM, but currently it is ridiculous.
