Fastest way to read a 600MB table (in memory)

$

 I cannot get more than 15-19mb/s is there any limitation that I need to know about?

The query is a simple select not doing sorting and the database is read-only : "select * from tablename"

Tried local and remote and still get the same throughput therefore is not a network problem.

Launching multiple queries in parallel bring the total time down almost linearly as I increase the number of parallel connections (which bring different sections of the data).

Finally the table fits entirely in memory therefore no DiskIO is involved either.

If someone has any insight, please chime in.
