That's true.

Last time I used MySQL that was true.

Some time ago I did a simplistic, but quite telling, test.

I had a large (several milion rows), indexed table, same data, in
MySQL (4.0.x) and PostgreSQL (late 7.4), on the same RHEL or FreeBSD
(don't remember) machine. Walking over the table with

SELECT * FROM TABLE ORDER BY pk LIMIT 10 OFFSET N;

or the MySQL equivalent, MySQL was several times faster than
PostgreSQL, but the times were getting longer and longer....
As N grew in increments of 10, it took ages for MySQL to return
the rows. PostgreSQL... Well, it was as "slow" with N=100000 as it was
with N=0.

How does *this* qualify as FUD? Or are *you* spreading FUD to scare
people from even mentioning the software?

I don't like MySQL. I hate it when people put cheerleading where reason
should prevail.
