Subject RE: Performance issue
Date Tue, 03 Nov 2009 13:34:53 GMT
I am connecting to the database from my .NET application (which uses Divan
as a library). But I've put it through a profiler and I get the large delay
when waiting for the response from the database. The time needed to run the
application itself (prepare the JSON message, parse the response etc.) is
minimal compared to the time it waits for the request. Actually sending the
request takes less than 5ms.

Anyway, I'll monitor everything with wireshark a bit later today and come
back with the results. Maybe, as Roger pointed out, my infrastructure is the
cause for this.
