LoadRunner supports multiple protocols, whereas NeoLoad supports only three protocols. With NeoLoad, we can go for the SAP technology, web-based HTTP, and Remote Desktop Protocol (RDP). If I have to simulate .NET application-based traffic, I won't be able to do that. So, protocol support is a limitation for NeoLoad. It should support more protocols.

One issue that we faced was that multiple users weren't able to work on the same application. We used to create multiple scripts based on the application and based on the projects, and then we used to integrate all of them in a single place. With NeoLoad, if you have to do this activity, to import a script, one user has to log off, and the second user has to copy the script and improve it, which is a time-consuming activity. These are the things that can block any further activity.

The SAP area could be improved. Not the GUI applications, SAP log-on, or something like that. We can see features and use NeoLoad properly in all the normal SAP log-on areas. I haven't tried it, but I have heard that Citrix-based applications don't work properly in the SAP application. In those types of different areas, there could be more protocol flexibility.

If there is a high number of users on NeoLoad—like around 5,000 or 6,000—it sometimes feels like that might be a bottleneck for the performance. That could be improved. With more users, there shouldn't be any issues from the tool side.

With scripting in a different browser, sometimes there are compatibility issues and it doesn't generate the script properly. Those types of crashes could be removed.

There were some features that were lacking in Tricentis NeoLoad, e.g. those were more into Citrix and other complicated protocols, which were supported easily by a competitor: Micro Focus LoadRunner.

What we want to see in this solution is how it integrates with the entire suite of Tricentis Solutions. Tricentis has a very successful product in Tricentis Tosca, and that is a product that is more focused on test automation. They have test management solutions. They have different management. Performance management or performance engineering within one solution would be a big winner for Tricentis NeoLoad, so this is an area for improvement for this solution. Otherwise, it is a really good tool.

I still need to take a closer look at the integration of Tricentis NeoLoad. I want to see how it integrates with other Tricentis products, because Tricentis did not have a good performance testing tool until now. This is a recent acquisition, so we want to see how these results come together: test automation, performance testing, etc., so that's what I'm looking for.

There are still some glitches that they need to improve. We have given support feedback as well when we have some issues. They're very responsive and they do work to fix and improve issues. 

LoadRunner offers a full protocol, whereas, with this product, only a few of the protocols are supported - not all.

We would like NeoLoad to be able to support more protocols.

Testing can also be a little tricky at times.

Tricentis NeoLoad could improve the range of codeless scripting such as with terminal emulation apps. 

Our issues with the solution were related to the license and the support. We had a technical issue related to our software and they weren't able to solve the problem.
