I did some benchmarking and in my setup there was major
performance difference.

I tested a ByteA column.

What was the test?


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.
