while you're in the area of a logon trigger, how about cranking up the db_file_multiblock_read_count, e.g.:

alter session set db_file_multiblock_read_count = 128;

to read 1 MB at a time, or whatever the max is that your OS will allow.

I never bothered tracing exp, but it works well for full table scans.
