RE: db_file_multiblock_read_count causing full scans to takelonger?

This is implemented at the port level. At least up until 8i there was a compile time #define value that established the max I/O transfer size. You could set dfmbrc to any large value you wanted but it was trimmed to fit within this compile time limit. I really doubt it has changed since then.
