Benchmark mySQL 5 and SQL Server 2000 - horrific!

I've experieced the same problem - here's a benchmark test.

Here's the query:

select learnercode,language,lastname,left(firstname,1) as 'in',gradecode as grade,
disciplinesnamelang2 as 'Detail'
from learners as a
inner join disciplinesaudit as b
on learnercode=auditlearnercode
inner join disciplines as c on b.disciplinescode=c.disciplinescode order by gradecode,learnercode;

The query returns 1817 rows:

In mySQL it takes 2 minutes 40 seconds - (say two minutes forty seconds)
In SQL Server 2000 it takes 1 second.- (say one second)

And, yes, it's the same PC, same tables in the database.

In fact the PC utilisation goes to 100% and pretty much stays there for long enough for me to think that the PC is hanging. The mySQL admin shows just about 0% utilisation.
