ESXI best setup

I just started helping at an office where they have a server with esxi 6.0 setup.

They have several servers and workstations VMs setup.

They use windows RDP to access the VMs

Things seem to work ok but also seem a bit slow on occasion.

What can I look for to fine tune the install??

Is there a better remote access solution to use that may work better??

1. Do the ESXI servers have enough physical ram and CPU cores to run all the VMs?

2. Do the VMs have enough cores per socket and memory assigned for the VMs (depending on the VMs memory and cpu usage)?

Could you give more information on which VMs are slow or is it everything?
Chris StandringSystems Architect/EngineerCommented:
Do you have just one physical host with ESXi installed?  How many guest servers are running on your ESXi host.  What are the specs of the server ESXi is installed on (number of sockets/cores, memory, HDD spindle speeds, what is the raid configuration), what are your guest servers using for resources.  
There are many things that can contribute to server(s) running slow on ESXi but we need to know some of the hardware specs of the host and also the guest servers settings to help out some.
As a quick guess, it could be an over commitment of resources of your guest servers.  It could be disk I/O, where you have a lot of data being written and read from the disks.  Network congestion when trying to access the servers via RDP.
If you can get us this info, it will help us with providing some possible solutions for you.

Well a lot of factors could limit the performance of your VMs but the first thing that comes to my mind is why to RDP....why they use they have slim terminals or they use VMs to cover a specific need....e.g. if they are all running an application i guess it would be better to optimize the application performance than to optimize the VMs...

I will gather some data and return and report

Also a screen shot of the VMs
Chris StandringSystems Architect/EngineerCommented:
Just at a quick glance, CPU usage is low, and your max available memory is getting close to being capped but you still have a little buffer should ESXi require more.  
Nothing is really standing out at me here that would state an over commitment of resources being the cause of slowness.  Have you looked at the performance tab and checked the results for your local resources?  If not, I would start with the performance monitor tab and look into any large percentage of use.  If I were to just guess from what you have provided... I would say it could be disk or network related where nothing else stands out.
What do you know about the disk and network configuration of this host?
Curtis LongAuthor Commented:
I know how to set up the disks and network interfaces.  As for setting up optimal configs......not a lot
Chris StandringSystems Architect/EngineerCommented:
Do you know what the current RAID configuration is for your local disks?  Are you using local disks or are you connected to a NAS/SAN/DAS?
Have you had a chance to look at your host resources?  You can find them when you click on the host and go to the performance tab.  From there you can choose from a drop down menu what resource you want to see.  Check out the disks and let us know what it is looking like.  When you get back to us, please also let us know (if you know) what the raid configuration is, the disks (HDD or SSD, spindle speed and size) are so we can see if it is a disk I/O problem.
