This is a bug in PyTables 1.1 (as well as in PyTables 1.2-b1). The
attached patch offer a *very preliminary* cure to this; however,
performance is very low for the kind of operations that you are trying
to do. This is mainly due to some naive code in the factory functions
for the NestedRecord object introduced in PyTables 1.1.

If you don't need nested records, please, use PyTables 1.0 for doing
benchmarking. PyTables 1.1 and higher will eventually achieve similar
performance (if not better), once this issue will be properly
adressed.

Cheers,
