Once we have designed a similar application and we witnessed slowness and performance issues. Thing is that, we can use start process to utilize load balancer but to get the output back from processes as request response we had to make use of activity chaining. Appian is not meant for such design, even the same is mentioned in docs/best practices also.

Agreeing with Stefan, this is not an ideal problem statement that Appian as a platform is intended to solve. Please contact Appian Support to get more information and suggestions.

The Appian platform is not designed for such tasks. I suggest to contact Appian to discuss this use case.

Go through EPEx once. You can take part in beta program for EPEx and check the result. I am sure that you would see a lot of improvement in performance.

Thank you for the response. We have upgraded the hardware to enhance performance, but the improvement has not been noticeable.

There is no strict requirement to use Appian. If we determine that the issue stems from Appian's limitations, we are open to exploring other technologies and then using Appian solely to initiate a process.

In my opinion using Appian to be used as webserver would be over stretching Appian limitations. Yes it can do that, but should we be using Appian for that ? if you have to use anyways have you considered upgrading the hardware to improve the performance.

Appian is also coming up with EPEx for high amount of processing in near future and that would improve the performance to great extend. you can read about that
