[DUG] Delphi vs C# for web services performance

[Leigh Wanstead]

Hi John,

I think that if you put a server closer to your user base, it should be ok
to use c#. If the users is in North Shore hospital, Auckland and if you put
your web server in the same lan network, you will get fastest network
response. The effect to use Delphi, C# is just minor matter compare to
network latency.

Your sql server logic will have bigger impact on performance than the
choice of C#, Delphi language.

Regards
Leigh
