Improving response time for NetWebServiceMethod
« on: December 18, 2021, 03:39:52 AM »
Hi,

My API app constantly has a 500ms overhead on any HTTP call. This 500ms does not include the work that is done in the ServiceMethod routine. A simple call then ends up taking up to 600ms to respond. I played around with the performance options on the NetWebServer template, but nothing there has the effect to change the response time.

I'm using NT 11.51.

Hi,
Any embedded code in Webhandler?
What database?
Local or remote database?
Cheers

Michelis,

I checked the timing of the code in the webhandler, negligible and less than 100ms (shows 0 when using duration with CLOCk).

The simple call I'm referring to, doesn't make any calls to the local MSSQL database. It just returns a value from a simple variable. So with minimal code in the ServiceMethod routine, there is always a minimum response time of 500ms.

Thanks

Alberto

Thys,
Did you try with a NTWS example?
Same problem?

Hi Thys,

are you testing on the same machine? over a LAN? a WAN? the internet?

I haven't tried yet. I'll do so.

Thanks
