Hi Carlos,
I'll try to run again the test profiling the Firebird provider.
We're using 2.0 embedded, but same results with 2.0 (in fact the lastest =
2 available) server.
We're running with both .NET 1.1 and Mono 1.x profile.=20
We're still using the "old" 1.7.1 provider with the "charset" fix (one =
we proposed long ago and you've accepted).
We have to continue using .NET 1.1 that's why we didn't move to a newer =
provider.
Thanks!
pablo
