Caveat: At the creation of the benchmarks there were a lot of VMs running on those 14 hosts (62) which have of course an impact on the performance of Fedora 4 since all machines share the I/O channels of one host. The hosts are connected via a 1GB/s network, and I think the two virtual partitions per VM are also mounted via this network. Im I am currently in contact with the folks at SCC to maybe get esxclusiv esxclusive access to a couple of physical nodes, so that other VMs dont do not slow down Fedora 4 perfomanceperformance.
When comparing D and E (with and without indexing), there should be an increase in performance, when turning indexing off. Since this is not the case I'm guessing that the I/O bottleneck is hit even earlier (replication over the network?) so that indexing does not slow down the ingest process at all.
