Regression of attachment fetching speed

I have tested the attachment fetching speed on two systems (FreeBSD64 jails, so same hardware), both systems had the same database (copied over). The script was using curl to get 20 attachments (sized 30-100KB) from different documents. The results:

system #1 (erlang 13B2, couchdb 1.0.1) typical time to run this script was 0.15 seconds
system #2 (erlang 14B3, couchdb 1.1) typical time to run this script was 4.5 seconds
