Default Parellism not working

We have migrated databases from SQL7 to SQL2000 Standard Edition. Now,
when we run queries against the newer hardware running SQL2000 we
notice that the execution plan shows no parallelism taking place. The
SQL2000 config. has 2 processors and both procs are enabled in the
Processor tab.(use all available processors is selected). I've
upgraded the install to SQL2000 SP3a but there is no change. Does
anyone know what may be going on here?

Thanks,
GC

Default Re: Parellism not working

Most queries will not benefit from parallelism. The optimizer will
choose a parallel plan only if it makes sense for a particular query and
the server is not overtaxed.

In many cases, a parallel plan is an indication that you need to do some
index tuning.

Hope this helps.
