Resolved this by installing *node.js* on the server, and dropping *therubyrhino* gem. Asset precompilation worked nicely, with no JVM segmentation faults. And, on y development machine, asset precompilation dropped from 2 *hours* to 7 *minutes*. T

Moving from jruby to nodejs? Therubyrhino gem? Could you please then explain your architecture? It's extremely unclear from your 2 emails. On 1st email I can see you allocated only 500Mb to your jruby job. I would advise for 1.5Gb if you're stuck on 32 bits, 2Gb and above if you're on 64 bits.

Rhino is not a fast implementation of JS - whether or not its integrated into JRuby via therubyrhino. Is anyone working on a therubynashorn yet? Chris

An excellent idea. Careful though: JDK8 is mandatory for Nashorn. And I understood just now why therubyrhino: rails complex stack for asset compilation. Why not sprockets instead?

THanks very much for the suggestion, Alex. I'll give that a shot and compare compile times. Tim On Sun, Jul 13, 2014 at 1:45 PM, Alex Tambellini <email@example.com>
