This helps with the locking issues. I believe the slowness was actually related to the index on the 'name' column. If I remove the index from the text field, then the inserts are much faster.
If I keep the index, the inserts eventually come to a crawl. Is 50-100 million with index on a text column an unusual setup? I've read some articles of folks storing hashkeys of the text values in a separate indexed integer column to speed up the indexing process.
