First call to Restful WS is too slow

Classic Servoy
1

Hi everyone, I’m experiencing an odd situation at a customer site. We have a Restful WS that the first time it is called after a period of inactivity, it takes around 90 seconds to respond while subsequent requests take 1-3 seconds. The WS works only with a POST request that receives an XML with authentication and other parameters. Each request is identical. This only happens at this customer site, the WS server and Oracle DB server are on separate VLANs. Before affirming its an issue with their network configuration (which makes sense since it only happens at this customer), I want to be sure of:

Is there any consideration in code (I only use a POST method, I dont use AUTHENTICATE or any other) or in Servoy server parameters or requirements, or connection parameters that could explain this behavior?

Thanks a lot for any input. Have a good day!

ps- I think the forum would benefit from a WebService topic, wouldn’t you agree? It’s quite different from other categories.

Look into the servoylogs and performance view when this happens. Maybe that gives a clue

Could be that this is the time the first headless in your pool is initializing. What kind of onSolutionOpen do you have on that solution?
I would check the performance of that first as well as look in the logs.

PS: As to a web services topic forum, you should check the Velocity project on ServoyForge, there is a forum there as well.
You would have many more options to serve and manipulate web services with Velocity! ;)
