Will this hit a system with EXT3->LVM->MDRAID1 particularly hard? Took
about two hours to do a local install (with a largish set of packages
but not everything) which I seem to remember took about 3/4 of an hour
before.
During installation ext3_xattr_block_set and r1bio_pool_alloc show as
the top guzzlers, totalling 1.5 billion allocations between them,
obviously plenty of disk writing going on ...
