There are definitely many site on Drupal for sure. Whoever says that
he is not aware of many sites on it does not know how popular Drupal
has become.

Drupal is resource intensive, Yes. It does lots of queries. Yes.

However, slow it is not.

There are many big sites running Drupal and they have low page
generation times (I have seen page generation times as low as 16
milliseconds, average is 100-300 ms, with spikes to 600 ms).

I personally know sites that do 930,000 page views a day, 59,000
per hour using the above averages.

Even on a relatively inexpensive Xen VPS (forget Virtuozzo or OpenVZ,
they are slow), performance is really snappy.

Because Drupal uses a lot of queries, it will be slow on shared hosts
that lump together lots of sites and their databases, or on sites that
have no PHP accelerators.

There are lots of resources on performance tuning and optimization
for Drupal web sites. There is one forum on drupal.org, as well as
a group on groups.drupal.org. 2bits.com has some articles on that as
Drupal development, customization and consulting.
