Anyone want to try the same with Firefox nightly?
Already did it and subsequently filed bug 873638. We can do it if we modify the encoding of the JS source at omnijar build time.
I did some measurements last year at the 2014 JS workweek and it turns out that the cost of converting the omnijar's JS source to jschars during parsing is equivalent to the benefits we gain from StartupCache. Assuming that nothing has changed in SM with respect to the time required to do the conversion, if we eliminate that conversion step, we can eliminate XDR-encoded JS from the StartupCache.
