[MonetDB-users] Optimal filesystem/platform choices for MonetDB?

We've started doing a big import of data into SR5 and I've noticed that it's creating *A LOT* of files. So far we've got about 620k files for 6.7 GB of bat. I expect that a full import should have at least 20 times what's imported so far. It seems that loading data is relatively slow compared to PostgreSQL (we're using COPY) and I'm guessing it's due to all of these files. Right now we're using ext3 on amd64 ubuntu linux. Should we be looking at other platforms?
