I did some benchmarking and in my setup there was major performance difference.
I tested a ByteA column. If I used ascii data the tests took 52 seconds. If I used random binary data the test took 250 seconds. binary data is (roughly) five times slower than ascii data? Is this a know fact, or is there something wrong with my benchmark? I used Python and psycopg2.
