> Using the page [https://www.guthriegreen.com|https://www.guthriegreen.com/]
> as a benchmark, a page fetch took about 100 ms, while simply *parsing* the
> json-ld content on that page took a *staggering 27400 ms*. For reference, I'm
> using Java 8, build 162, on a Macbook Pro (early 2015).
> The bad news is that this is not our fault.
> I've profiled this behavior down to the
> {{com.github.jsonldjava.utils.JsonUtils.fromURL(URL, CloseableHttpClient)}}
> function. 94% of the parsing time is spent there. This function is called
> when trying to load remote json-ld contexts.
> In order to avoid loading remote contexts repeatedly, this function tries to
> *cache* them by using a {{CachingHttpClient}} from the httpclient-osgi
> library.
> Unfortunately, that strategy is *not* working, as I have recorded exactly
> *zero* cache hits, meaning that *every* retrieval is a cache miss and a
> remote context is re-fetched via http every single time it's accessed.
