Net::LDAP vs ruby/ldap

The basic premise of this test was to see how long it would take to do
the following:

1000 Basic lookups on a known attribute/value pair over an unencrypted
connection using anonymous bind for each library.

This post is for informational purposes, I knew the NET::LDAP lib
would be slower but I wanted to see by how much.
{if you are new to ruby, the reason it is slower is because its a TRUE
ruby implementation of the LDAP rfc. while on the other hand the ruby/
ldap lib is a C front end to the openldap library}

Bottom line is -- I just figured i would share.
Code:
----------------
require 'benchmark'
include Benchmark

LOOP_COUNT = 1000
require 'ldap'
require 'net/ldap'

HOST = 'somehost.com'
S_ATTR = 'some attribute that exists that can be lookedup'
S_VAL = 'a value for the attribute that iss valid'
TREE_BASE = 'a valid base ex. o=com'

class LdapTest

def net_ldap_test
ldap = Net::LDAP.new :host => HOST, :port => 389
filter = Net::LDAP::Filter.eq( S_ATTR, S_VAL )
ldap.search( :base =>TREE_BASE, :filter => filter ) do |entry|
a=entry.dn
end
nil
end


def ldap_test
conn = LDAP::Conn.new(HOST, LDAP::LDAP_PORT)
filter = "(#{S_ATTR}=#{S_VAL})"
conn.search(TREE_BASE, LDAP::LDAP_SCOPE_SUBTREE, filter) do |entry|
a=entry.dn
end
nil
end

ldap_test=LdapTest.new

Benchmark.bm(15) do |x|
x.report("NET::LDAP:") { for i in 1..LOOP_COUNT;
ldap_test.net_ldap_test; end }
x.report("ruby-ldap") { for i in 1..LOOP_COUNT ;
ldap_test.ldap_test; end }
end
end

While it's interesting, I'm afraid I have to stick with net-ldap. The
problem with ruby-ldap is that it segfaults in conjunction with
WEBrick, as I know all too well.

my good friend justin crawford works heavily with ruby and ldap for the
universtiy of colorado managing a huge federated authentication system. they
use the pure ruby ldap lib because the c version is unstable. he's been using
it for several years on a system that's serving ~ 100,000 people - so i think
it's fast enough.

fyi.

I'd be interested to discover exactly what "unstable" means here, so
that I can fix the problem.

I'd also like to see code that can reproduce the segfault in
combination with WEBRick.

Thanks,

Ian
