[DUG] Delphi vs C# for web services performance

[John Bird]

Current version (Hospital Java app)  used to have a requirement that the DB returns each result within 200ms (fires about 15 simultaneous queries to various systems including 2 or 3 to ours).

Currently the calls are to stored procedures on a SQL Server cluster to get the data.   The web service (Delphi or C#) would put a layer between the application and the DB, packaging the query results into XML or JSON and its pretty critical to get as close to the direct DB access speed as possible.   At times being a hospital system the load is high and the response times are crucial.

Hi John, 

What is your requirement for performance?

i.e. One million user to get median value 100ms response time?

Regards
Leigh

  There is a web service we might are looking at implementing.   We could use
  either Delphi or C#.  Performance is highly critical.   Will be getting
  getting REST request, getting data from a DB. and packaging it into XML or
  JSON according to the request.

  We have noticed that some C# web services have some latency but  this might
  be due to how they are setup on IIS rather than an inherent language issue.

  We are wondering if there is any clear reason to do it in Delphi - anyone
  have metrics or references etc on performance?
