The answer is an apples and oranges situation. Alfresco is really
built for document management. It can also serve web sites. Silva was
built for content management. It can also store documents.
However we don't recommend Silva (actually, the limitations are in
Zope) for storing *large* numbers of documents. At least not out of
the box. Various add-ons help to alleviate the storage problems, and
the recent arrival of blob storage in Zope has made document storage
A number of years ago Infrae wrote a Document Library application,
which *is* a DMS, and integrates seamlessly with a Silva website using
the OAI protocol:

The organizations have taken varying approaches. ETH has a large
installation with some 450 websites running in one Silva (each site
has a separate url). ETH has in-house developers.
Most large organizations operate a ZEO cluster, sometimes with
separation of concerns (such as editing or special instances for bot
visits). All large organizations use caching, most often Squid.
All the orgs have customized skins. Most have custom content types,
usually an extensions that integrates with an external data source,
such as a course or user database. But some, like University College
London, have also extended core content types like Silva News Network
and made those available.
