The blockchain checkpoint in this release has been updated to 216116. I created a bootstrap.dat of this height and successfully imported it in 37 minutes with bitcoin-qt on Win7 64 bit. This bug appears quashed:
https://github.com/bitcoin/bitcoin/issues/1951Using one of the fastest SSDs made, Bitcoin is CPU-limited and thread-limited, holding one CPU core at 100%, and blipping a second core to ~75% every few seconds.

I will offer this as a torrent and also give direct-download links to those who wish to jump-start and seed such a torrent, since my seeding speed is limited. The question is, should an official torrent going forward be a compressed file? Using the highest compression preset with
xz/lzma (installed with most distros, opens with 7-zip or
MacOS GUI tools) saves 2GB of downloading, so I say yes:

Also, bootstrap.dat is too big for FAT32, but not the compressed version. Bitcoin 0.9+ could even (feature request) open a compressed bootstrap (lzma is a stream container) directly if standardized.
