I speeded that up in squeaksource3 by caching the listing on squeak and pushing that as txt.
(see SqueakSource-Caching-Core-topa.2 for the model side and SqueakSource-Core-topa.104.mcz for the view part, especially SSRawDirectoryListing and 

SSUrlFilter>>rawListingOfProject: 

rawListingOfProject: projectName
	<get>
	<path: '/{projectName}/?format=raw'>
	<produces: 'text/plain'>

	self projectNamed: projectName do: [ :project |
		(self isAllowed: SSAccessPolicy read in: project)
			ifFalse: [ self authResponseFor: project ]
			ifTrue: [ self requestContext respond: [:response |
				response nextPutAll: project rawDirectoryListing]]].

in http://www.squeaksource.com/squeaksource3.html )

TL;DR: serve the directory listing as plain list of file names when ?format=raw is requested. Only invalidate this listing when a version is added or removed.
