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.
