Hello,
We’ve been migrating our fairly large Rails 1.2 application from MRI
1.8.6
to REE 1.8.7, and in the process we’ve encountered some fairly odd
behavior.
Namely, instead of the expected reduction in memory usage, we’re seeing
an
increase in memory usage by around 40% and, along with it, an increase
in
processor usage.
The stock 1.8.7 implementation performs even worse than REE from both
standpoints, and while this is somewhat redeeming of REE, something is
most
definitely amiss.
Tweaking REE’s GC parameters was our first instinct, but the
improvements we
got that way were negligible.
The question is, has anyone experienced anything similar? Is there
something
we’re missing?
If there’s anything I’ve left out that might be helpful, please point it
out
and I’ll be more than happy to answer.
