Split out of issue #1429. Data from there reiterated here for convenience. "it's pretty obvious that libsvn_wc is a pretty huge performance hit, and so is the dav layer." libsvn_wc is making a checkout over ra_local be 3 times as slow as an export without eol translation or keyword substitution. That is, it takes 200% more time! Over ra_dav the difference is less noticeable, indicating that there is enough lag in a checkout over http to overshadow the working copy slowness partially. Here, a checkout takes 23-29% more time than an export without translation or keyword substitution. In any case, we can point a finger to libsvn_wc. Simple profiling data to follow shortly.
