Yep, anything in memory will be at least an order of magnitude faster
than disk access ( yes, cache aside, ) if you have it to spare. Especially
here, when it seems there is no reason to store the data ( always available
from another server. ) Even if you needed to keep the data, not sure why
you would access it every 5 seconds when you know it is updated every 10
seconds.

So every HTTP GET request to the webserver spawns a separate process to
fetch and process the quote data.

per request by spawning multiple threads.

webserver per every HTTP GET request.
