Subject: use list comprehension instead of generator as it is much faster for small
X-Git-Tag: rel_0_6beta1~185
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=d00ee6bf566a14c39ce747952ade0790c658fd95;p=thirdparty%2Fsqlalchemy%2Fsqlalchemy.git

use list comprehension instead of generator as it is much faster for small
lists, as will usually be the case here. provides a ~11% speedup for large
column-only queries.
