Does "to process into the index" include time for transport and/or
block validation (presumably by bitcoind) or this this exclusively the
time for Electrum Server to index a validated block?

look at how the Electrum server software handles under load. The
Electrum wallet is extremely popular, and the distributed servers
which power it are all hosted by volunteers without budget. The server
requires a fully indexed Bitcoin Core daemon running, and produces
sizable external index in order to allow SPV clients to quickly
retrieve their history.

takes this server (Xeon, lots of memory, 7200 RPM RAID) approximately
3.7 minutes per megabyte of block to process into the index. This
seems to hold true through the 10 or so blocks I have in my scroll
buffer, the contents of blocks seem to be of approximately the same
processing load. Continuing this trend with the current inter-block
time of 9.8 minutes, an electrum-server instance running on
modest-high end dedicated server is able to support up to 2.64 MB
block sizes before permanently falling behind the chain.
