My best guess is that you are running into a caching issue. The DocumentLoader does cache documents that it has read in the past (although normally this cache is 'cleared' between main document loads). It is mostly present so that if you pull in 50 symbols from the same document we don't reparse that source document 50 times.

Sorry that last sentence made my head spin a bit :)
Say i have a doc loaded for the first time with 10 <g> elements, each with 100 distinct <path> elements, how would this work then ? Why would you have to reparse the source document 50 times?
You wouldn't, but if instead of using path elements you used the 'use' element point to 'symbols.svg#sym1', 'symbols.svg#sym2',...
Without the caching we would read the entire symbols.svg once for each use element (something similar happens for image - because we consider images static). The caching allows us to only parse the file 'symbols.svg' once and just lookup the symbols in the document as needed.
As I said it is unclear why the load cache isn't cleared between loads of toplevel documents although this is the only thing I can think of that might explain a large performace difference.
