I have not had the opportunity to use this scalability feature of the product, but I know that it depends on the machine or the hardware on which the tool is loaded. I would say that it is a scalable product since it is a software-based solution.

I can speak about the services being used on the product since there is no user interaction required with HAProxy. I can say that my company uses more than 50 services on HAProxy.

It is scalable. We haven't experienced any major issues with scalability. We didn't need to apply any specific scheduling to the system. We have up to 1000 users in our company.

The solution is easily scalable. If I were to run out of CPU space, or memory space, it would be very easy to just take my rules and virtualize them into VMware, and get a much more powerful solution. The other choice is to get another pair of servers and use the load-balancing functionality that comes with them to go between the two server environments.

We have publicly permitted our web application for this, and approximately 5,000 users are using it.

It is used every day because it is our production-related order-lease domain or something along those lines. We are also using this as a dealer, with approximately 5,000 users per day.

Normal users. We will publish it on one of the websites that provide the production information. We provide the order and invoice the order to the product. These are the types of details. This is our dealership's publisher for an automotive dealership.

It is essentially the dealership's publisher.

HAProxy is scalable. There are plans to expand to the Japan team. They may suggest a paid tool.

HAProxy is scalable. We have some 2,500 end users using HAProxy. They are mostly developers. 

It's a scalable product.

There are more than 2,000 users on the product right now. 

We already scaled up with the different sets, so we previously scaled this solution.

We had no problem with scalability both in terms of scaling HAProxy itself, or the backend behind it.

It provides impressive scalability. I would rate it ten out of ten.

The scalability of HAProxy is good.

We have approximately 10 servers utilizing this solution.

Our organization is an enterprise, but we are using HAProxy for the basic requirements and functions. We are using the basic requirements for load balancing. I would recommend this solution for small businesses. For large businesses, I would recommend Citrix and F5.

HAProxy is scalable. It easily handles the current loads, but my connections are pretty low. It can take a lot more than what I'm doing. I'm making around 200 connections per second, which doesn't put much stress on the solution. HAProxy can handle it pretty easy.

We have good scalability. 

No issues with scalability.

Yes, there have been issues with scalability, but that's because of other software configuration such as OS settings, network.

None, so far.

The tool is scalable. We have everything we need.

No scalability issues, ever.

No scalability issues, but only because we do not deal with a lot of scale here. We simply rely on an active/passive configuration, so if a load balancer were to fail, we would have a backup instance ready to go.

No. The implementation that Carers ACT undertook is focused on reliability over scalability. The throughput required is low, but reliability requirements are high.

The solution is scalable. 

I do not see enough traffic to make an honest critique of the stability.

Full layer 7 SSL termination is limited to a single core, which is a problem. We have worked around it terminating SSL on the back-ends, but this is not ideal.

No issues with scalability.

No issues. I have about 500 users on HAProxy, which use a web server and mail server.

There were no scalability issues.

No scalability issues.

No issues with scalability, but multiprocess config for HAProxy is more efficient than multi-thread.

No issues with scalability.

We are still in the process of rolling out our deployments and migrating our traffic.

I haven't had any issues with scalability but, as I mentioned above, some reviewers have said that NGINX is able to handle more connections than HAProxy.
