Hi,
i know that there are no real performance tests done,
but my simple tests shows me that with the actual src the type 4-driver is about 2 times slower with simple selects (like "select * from table where id>0") than interclient.
With inserts or update i have no problems, but in my aplication tehere are no mass inserts so i could test it.
