> Turns out that with a large enough libsoup cache, the soup_cache_load method takes quite some time to execute - roughly 10% of the whole time is spent in either g_variant_iter_loop or in g_list_length that's called by soup_cache_entry_insert in soup_cache_load.

Yes it's a known issue. There are a couple of bugs in libsoup where I started some fixes for that. The main issue is that we load all the HTTP headers when loading the cache. There are different approaches to fix that, but I never found enough time to completelly implement them.
