Yes and no, therefore I mentioned it explicitly as one of the caveats. When doing selects I could get performance very
comparableto MySQL, so I don't want to blame poor insert-performance on cygwin/cygipc per se. 
I'm not working on this app. anymore and don't have a working test-environment for it anymore so I cannot retest now
withmore recent versions.

What MySQl-table-type did you use?
Was it "MyISAM" which don't supports transactions ?
Yes I read about that bulk-inserts with this table-type are very fast.
In Data Warehouse one often don't need transactions.
