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.
