I'm thinking in CPU-bounded parts of a request: Reindexing, Clustering,
Automatic Content Extraction, and the like...

We have implemented k-means clustering algorithm on top ZCTextIndex (now
plan to port to zc.catalog), although this is batch operation, some
other are per-query: Summarizing is one of those: Per cluster, and per
document. (Although this is maybe a question for the OTS list).

So I'm a little bit worried about how the resource utilization.

Best regards,
