SW Performance / Possible Memory Issue?

I'm using a Lenovo Thinkstation D20 with Windows 10 Pro 64-bit. The graphics card is a NVIDIA Quadro FX 1800 & I'm using the certified SolidWorks driver (version 341.96). 8GB of RAM, (2) Intel Xeon processors (2.13GHz).

At home I use a Dell Precision M3800 laptop and it's noticeably faster than this machine - I don't think that should be. Everything seems to lag in SolidWorks. I get frequent pop-ups from the SolidWorks resource monitor saying that available system memory is low. The memory page of Device Manager is below, & of Resource Monitor further below. Is this just a memory issue (not enough)? Anything else I can check?

Thanks....
