I have a 2009 cMP. 3x2.66
48GB
10.11.3
This is my main machine. I do TONS of web surfing on it.
I use Chrome with several windows, each including20 (static) tabs usually.
My boot drive is 256GB SSD connected to a PCI-E and it has about 200GB free space.
I have several 3.5 sata drives.
I do run a few VMs (3 max ever) running Windows via VMware Fusion and they are tailored properly.
I do use Chrome as my browser.
Is Chrome the culprit?
Since moving from Yosemite to El Capitan (via clean install and manual update / import of data) I have seen the web browser slower and OS a little slower.
I have a good amount of stored data in SATA on this unit, I don't want to get rid of.
My video adapter is nvidia GT 640 (double slot, does not need extra power connection(), no display at boot.
My particular needs are a little different.
While I don't NEED to run the latest OS on THIS machine, I do need to run latest and greatest on a few boxes to do my IT TECH training on them.
