-------------------------------------------------------------

[~p_ansell] Given that your PR #224 will effectively neutralize the _added_ 
speed advantage of my first branch over my second branch in most cases, I've 
gone ahead and submitted a [pull 
request|https://github.com/jsonld-java/jsonld-java/pull/228] for my second 
branch, after renaming it "issues/#227" to align more closely with your 
existing branch naming conventions.

Please let me know if there's anything else I can do to help!

> 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.
