I would like to make a PLC program and very limitted web server demo just in case a customer wants to buy like additional feature. What is possible to implement, or what features in webserver really "eats" load and work memory?

It was rarely used so disabled it on future projects.

With a little thought, the design of the custom web page can take very little 'juice'. For examples, see Pegaia's tips. Things like using a single DB for all custom user web page tags so they can be retrieved in a single lookup call. And yes, a higher refresh rate (10 second or 20 second or on demand is even better) helps reduce overhead. If you want it to be a live page with constant updates, it will consume plc resources. If you have any closed loop control like PID or motion, you may find the user web pages can have an impact if the system comm % is not increased from the default. Just some ideas. If you find others, feel free to add to Pegaia's thread.
