addblocks creaks to a halt

[kulpreet]

I tried fetching data from a bitcoind peer, but that creaked to almost a halt.

So then got my hands on a bootstrap.dat and tried importing it. With txindex and addrindex not selected, addblock still creaks to a halt.

The interesting part is when it drops from processing >1000 blocks in 10 seconds to 5.

This is on a spinning disk, could that be the cause? Could that be the only cause?

I am happy to look into this, but I am sure some people have excellent ideas about what needs to be done - if anything, i.e. A hint or two will be useful to nudge me in the right direction.
