Site#list is much slower than Site#lists

[IndigoCZ]

The following is very slow(100+ seconds):

c = ActiveSP::Connection.new(...)
my_list=c.root.list(list_title)

The following is very quick (7 seconds):

c = ActiveSP::Connection.new(...)
my_list=nil
c.root.lists.each do |list|
    my_list=list if list.Title==list_title
end

Tested on savon-xaop (0.7.2.7), ruby 1.9.2p180, Sharepoint 2007

I discovered that when using the lists method, the delay kicks in when I first call a method (column name) on an individual item. I ran that call through the profiler:

The #list method actually returns the list with list_name in the URL, which can be different from the title.

It is kind of annoying that Savon insists on parsing the XML returned by SP with Crack. Crack uses REXML which is very slow. We use Nokogiri because it is faster and is still maintained.

[IndigoCZ]

Is there any chance of Savon switching to something other than Crack?
