This particular trick is a clever one (that I'm afraid I've had some
hand in propagating, for the benefit of those that like an "auto" +
browser refresh workflow), but it's never going to be particularly
efficient. By its very nature, pdo sets up cljx and cljsbuild off and
running without any coordination; it's equivalent to running the two
tasks in separate processes.
It's possible that some hooks may become available in cljsbuild so that
things like cljx can do what they like prior to each compile, but that's
speculative.
IMO, a REPL-based workflow is far superior to anything involving
reloading your app's page, insofar as you can (nearly always) apply the
changes you're working on without blowing away the state of the app. In
this context, cljx's nREPL middleware excels (but unfortunately cannot
be used with the stock ClojureScript browser-REPL; check out Austin).
Note that cljx has not been optimized _at all_. It's "fast enough" for
my purposes (i.e. reasonable when doing a clean rebuild, and snappy when
doing the small changes typical in a REPL). I'd be happy to merge
reasonable patches that make the actual cljx transformation faster.

However, maybe perhaps it's weird timing interaction between cljx and
cljsbuild that's making the lag appear more than it actually is.

Unless you're compiling a very large file - with auto :optimizations :none
you should always get sub-second compile times under auto.

are you using "lein cljsbuild auto" ? That's what I use, and I get about
1-3 sec recompile times for stuff that uses core.async.

Hi,
* I'm already using:
:incremental true
:compiler { :optimizations :none }
* I'm also aware of cljs brepl
However:
1) the cljs compiler is still too slow for my liking (even though it's
not calling closure)
2) I don't like the cljs repl nearly as much as I like the clj repl
Now, my dumb/stupid question:
Is there any cljs in cljs _slow_ interpreter? I'm perfectly happy
with an interpreter that runs 10x slower, if, in exchange, I get to
hit "refresh" and my new code starts running.
Furthermore, I'm _okay_ with their being a big delay every time I
introduce a new macro from clj land.
I realize this sounds spoiled -- but -- the cljs compiler delays are
really really breaking my flow.
Thanks!
