How big is your search database?
What does "indexer -S" return?

- crawling is not CPU consuming,
   it can co-exist with indexing and search without any problems.

- indexing and search are CPU consuming


For small databases (e.g. less than 100k documents) having is single
box for all three tasks is fine.

For bigger databases with a few hundred thousand documents a box with
multiple CPU cores can also handle all three tasks.

For huge databases with millions documents separation makes some sense.
However, instead of separating crawling/indexing/search tasks, I'd
propose to consider using cluster solution described here:
http://www.mnogosearch.org/doc33/msearch-cluster.html
It significantly improves search performance.
