FYI: Just finished a big study on native drivers versus ADO.Net on my BLOB imaging project. The average DB response time for a 4K average blob image was 109ms for ADO.net and 16ms for the native driver. The testing was conducted using PB Classic and PB.Net v12.1 over to ASE 15.3 & 15.7. DB write times for the Blob Updates averaged 31ms for the native driver and 174ms for ADO.Net
BTW: PB Classic was timed at 33% faster than PB.Net on the same blob test (read & write) over 114K rows.
Interesting .... n'est pas?
