Nice one, [~phloy]!
bq. Hi Philip - can you show some 99th percentile measurements of a cluster
receiving a decent amount of concurrent requests? With and without your patch?
+1 for this - I'd love to see the same.
Also, another idea:
I'm assuming this patch *always* sends an extra request right away. How about
sending just 1 request first and then *firing the 2nd one only if the 1st one
hasn't returned after N milliseconds*? This way the price of an extra request
will be paid only sometimes. Using N=-1 or N=0 could mean "send both right
away".

> Add the ability to configure the built-in solr load balancer such that it
> submits a backup request to the next server in the list if the initial
> request takes too long. Employing such an algorithm could improve the latency
> of the 9xth percentile albeit at the expense of increasing overall load due
> to additional requests.
