vSphere 6 Performance

Understanding and Tuning ESXi 6 and VMs for Best Performance | taught by Larry Karnis

Course description

The efficient use of ESXi 6 host resources, proper ESXi 6 host hardware sizing and configuration, and the correct sizing and configuration of Virtual Machines are all critical to scaling up your vSphere 6 environment. This this course we will look at how ESXi 6 uses physical server resources, the strategies it employs to efficiently use resources and what we can do to help ESXi 6 scale up efficiently.

In this course you will learn:

  • How ESXi 6 manages physical host CPU to meet the CPU needs of VMs
  • How to size VM CPU to maximize overall ESXi host CPU utilization
  • How ESXi 6 host memory is efficiently managed using five memory management techniques
  • The purpose and benefits of Transparent Page Sharing and how to enable this feature
  • How to correctly size VMs for modern Non-Uniform Memory Architecture (NUMA) enabled servers
  • About Storage I/O Control and how to use this feature to enable fair disk access during periods of high I/O use
  • How to use Overview and Advanced Performance Charts to review and monitor ESXi hosts, VMs and more
  • To detect high Host CPU over commit by tracking CPU Ready time
  • Strategies for coping with high CPU over commit
  • Strategies for coping with high Memory over commit

The correct sizing and configuration of ESXi hosts, Virtual Machines and storage is critical to delivering superior Virtual Machine performance. In this chapter you will learn how ESXi uses hardware resources and strategies you can use to maximize VM performance.

Get VMware vSphere & View Training... for less!

Q: What do you do if you need to learn VMware but can't afford the $4,000 - $6,000 charged for authorized VMware vSphere training? 

A: Enroll in my equivalent VMware vSphere 6.5 and Horizon View video-on-demand training... for less.

Many name is Larry Karnis - and I create courses that will help you start your career as a VMware vSphere 6.5 administrator, and help you build you knowledge and skill in vSphere 6.5 advanced features and capabilities. 

With Video-On-Demand training, I can provide more insight and detail, without the time constraints that a normal instructor led training class would impose. My goals are to:

  • Give you a better training experience than classroom training
  • Help you learn more than you can learn in a 5 day class
  • Give you the opportunity to learn at your own pace
  • Provide you to supporting books and hands-on lab rentals

At price points that you (or your boss) will appreciate.

About Me

I am an Information Technology consultant / trainer with over 30 years of experience in system administration, networking, security, infrastructure and security.

I worked for 10 years as a UNIX programmer / consultant before moving to Linux in 1995. I started working with VMware products in 2001 and decided to focus exclusively on VMware in 2004. I earned my first VMware Certified Professional (VCP) designation on ESX 2.0 in 2004 (VCP #: 993). I have also earned VCP in ESX 3, and in vSphere 4 and 5.

My VMware Work Experience

  • I have been providing VMware consulting and training for more than 14 years. I have lead literally hundreds of classes and taught thousands of people how to use VMware. I teach both introductory and advanced VMware classes.
  • I worked for VMware as a senior contract VMware Certified Instructor (VCI) and consultant for almost 5 years. One of my regular duties was to help mentor new VCI's - helping them prepare for and successfully deliver vSphere classes.
  • After leaving VMware, I launched my own training business focused on VMware virtualization in 2008. In 2013, VMware called me back to help them ramp up support services for the upcoming vSphere 5.1 product launch.
  • Prior to VMware, I worked as a contract consultant / trainer for RedHat (I hold RHCE, RHCI and RHCX), Global Knowledge, Learning Tree and many other training and consulting companies.


I hold a Bachelor of Science degree (majoring in Computer Science with a minor in Math) from the University of Toronto, Canada. 

I also hold numerous industry certifications including VMware Certified Professional on VMware Infrastructure 2 & 3 and vSphere 4 & 5 (ret.), VMware Certified Instructor (ret.), RedHat Certified Engineer (RHCE), RedHat Certified Instructor (RHCI) and RedHat Certified Examiner (RHCX) as well as certifications from LPI, HP, SCO and others.

I hope to see you in one of my VMware classes very soon... If you have questions, please contact me directly.
