VMware vSphere Performance

Have you seen a performance boost for these apps? If yes, by what percentage?

We have seen performance boosts. Although I can't give you an accurate number, I would estimate it at about a 40 percent increase.

We have seen performance boosts for our mission-critical apps, with the ability to add compute at any time. We've been using this for so many years, so over that time we have probably seen performance increases of three to four times. As compute has increased we've been able to offer that to the apps. I don't know that I can give you a total percentage increase but it's a lot.

We are able to increase the density of the virtualized servers and, with the increased density we have a lot of page sharing as well as memory sharing. We see performance increases from Server 2012 and forward

We are spending less on buying bigger machines, which are overprovisioned. Thus, the ROI is found in consolidation and cost savings.

We have absolutely seen a performance boost, in particular with some of our legacy applications. For some of the legacy apps, we have seen at least a 75 percent increase. In addition, some of the newer applications have also seen a boost because they're just more efficient running on VM rather than on bare metal. For the newer apps, depending on how they're optimized, the increase has been at least 10 percent.

As soon as we switched over from Workstation to ESXi and vCenter, the downtime was very minimized. Growth and flexibility are now there. If I want to add more hosts, servers, and devices, it is not a big deal. The infrastructure is there. As far as having more job requirements, we wanted to explore our development lifecycle more without making major changes.

I would think there has been a performance boost. I don't know exactly what percentage, but maybe five to ten percent.

There is an average performance boost, especially if you use VM encryption inside the VMware with another product, like McAfee. You will see great improvement in these cases.

As far as performance on vSphere goes, the performance is great. We've been running everything virtualized from VMware forever, so I can't really say that there has been a boost in performance, but I can tell, from version to version - and now out on version 6.7 - that everything is continuing to be better, faster, and stronger in everything that it does.

VP of Product Engineering at Navisite
When I look at the performance aspects, I've definitely seen a reduction over versions from the virtualization penalty. This has been significantly reduced over the years. The size limitations of VMs, number of CPUs, amount of memory which can be allocated, and amount of storage which can be allocated are no longer of practical consequence. So, the monster VM that we talked about over VM Worlds of three to five years ago, they're here to stay, and those limits are no longer practical impediments to virtualization.

In regards to a performance boost, I don't know at the application level, but I can tell you, purely at the vCenter level, that we have seen improvements in our ability to migrate from Windows to the appliance, now that there is full feature-parity across the stack. We're seeing reduced resource usage from the appliance, it's way more efficient in 6.7. Operations are able to complete faster, so we're happy.

We have seen a performance boost compared to the previous versions, like a 5.1, five years ago. It has gradually increased.

We've seen an increase of about five to ten percent for the mission-critical apps. Their code is a lot more optimized now that they're using it in the public cloud with VMware Cloud on AWS.

I don't have a percentage for the performance boost of the apps. However, there is noticeably different speed of how the database is working and how you move through the client. Everything is a bit more responsive. Part of that was getting rid of the flash client as well. We're seeing an overall general performance increase in everything we do, whether it's the monitoring aspect or deploying.

I have seen a performance boost in a sense that we have provided better utilization of system resources within vSphere. However, I don't have an actual percentage to provide.

We have seen a tremendous performance boost. From when we started this VMware engagement in 2016 until now, we have seen around a 70 percent performance boost. This is a good number.
