Leif Hedstrom commented on TS-423:
----------------------------------
I'm going to increase this to 2048 I think. Here's my thinking, the default is
way too small. and we need something somewhat reasonable. 2048 in-flight DNS
requests could equate to maybe 4 - 8k QPS or so, which we really should be able
to handle. If the resolvers can't handle that sort of load, they really ought
to increase their resolver capacity.
Anyone against?

> Currently, the default for max number of DNS request in-flight is 60. This
> seems awfully small, particularly for a forward proxy. What if we increase
> this to maybe 512, or some other large'ish number? What is a reasonable,
> default "upper" limit? I assume this setting is there to not kill the
