This is basically what we have done, with drupal 5 running on a single
box. We aren't using memcache yet but we *are* using squid. Apache
bench output using regular caching looks like this:

Concurrency Level:      5

Requests per second:    98.85 [#/sec] (mean)
Time per request:       50.581 [ms] (mean)
Time per request:       10.116 [ms] (mean, across all concurrent requests)
Transfer rate:          963.79 [Kbytes/sec] received

I would expect for this test that almost all of it was served out of
the squid cache actually, but for performance for users that are
*logged in* APC and MySLQ 5 query caching are the biggest bonuses, and
these are something the host should *want* to do for all of their
customers to reduce processing demands on their boxes.
