I do not think this would be hard,
but see below.

Yes, "svn ls -R" is terribly slow.
See this

I believe Jean-Marc Godbout has created a patch that speeds things up
quite a bit, but
1) his patch does not achieve a factor of 100,
which IMHO would be reasonable.
2) AFAIK, his patch never got integrated.
As a workaround, we created a tiny cgi-bin shell script that
uses "svnlook tree" directly on the repository to output the tree.
This works with subversion as it is and it also does achieve
the factor 100 speed up.
I am using the following python function to connect to
the server, get the tree listing and convert it back to
the "svn list -R" output format:
def list_r(url):
""" get a recursive listing of url. """
list_lines = []
try:
import httplib
# open a connection to cgi-bin/svndir, which returns a directory tree
# with leading spaces that indicate the depth.
url_components = url.split('/')
connection = httplib.HTTPConnection(url_components[2])
connection.request("GET", "/cgi-bin/svndir?" + '/'.join(url_components[3:]))
# Convert into the format returned by svn list.
path = []
for entry in connection.getresponse().read().splitlines():
spaces = entry.count(' ')
path = path[0:spaces]
if entry[-1] == '/':
path = path + [entry[spaces:-1]]
list_lines.append('/'.join(path) + '/')
else:
list_lines.append('/'.join(path + [entry[spaces:]]))
connection.close()
list_lines.sort()
# Do not care what went wrong.
# In any event try using svn list -R if cgi-bin/svndir fails to return lines.
except:
pass
if list_lines == []:
print "svndir returned no entries. Falling back to svn list."
list_lines = subprocess.Popen("svn list -R " + url, shell=True,
stdout=subprocess.PIPE).stdout.read().splitlines()
return list_lines
