RDFDataMgr should be faster, but would be used by model.read() anyway after its initialization.
It is also possible to do streaming reads, where you get each triple as it is read (and no Model). Combined with streaming writes this is the fastest way to do format conversions (e.g. RDF/XML to Turtle). If you need to shuffle RDF between different Jena instances you might like the binary Thrift-based format which can be significantly faster and more compact than the rest. What kind of Model are you reading into? Memory or disk-based? For tdb there is the tdbloader and (on Linux/unix) tdbloader2 utilities you can run from the command line. Apologies for not having any links above as I am posting from mobile, I am sure others will fill me in where needed.
