That link (I removed it because it looked like spam) said that defragmentation can make a hard disk slower (in fact: not at all or hardly noticeable for an SSD) and advertised a Windows program to keep it defragmented. That's a bad idea for an SSD, and very unlikely to be the cause of slower performance on a webserver. It could even be a Linux server for all we know.

You'll have to analyse the cause of the slowness, or if you can't find that yourself, hire an expert or a company.
It can be that you need another server or more RAM in the server or a faster network or optimised settings in the server, the VM or the application.
But don't exclude the option that it's just a bad application that slows down because it doesn't correctly handle the increasing amount of stored data.

have 10 VM's sharing 16GB of ram. If all 10 are up and being used that's at little over 1 gb per VM. Plus you have the apps and SQL on the same VM. HD's using raid technology are more common for servers. Also most servers use Xeon processors. I suggest 64GB of RAM.

A few more thoughts.

That's a lightweight server so I'd think it's working pretty well given the story. But.

1. Check your SQL code for performance sucking gaffes like:
SELECT *

2. No matter how fast or bad @ss your server is, there will always be calls for it to be faster.

3. For this many users it's a light weight server. Not enough cores, RAM and what looks like a non-RAID storage system. Budget may not allow this to change so take solace that it all works and campaign for more or better servers.
