Items evicted from cache are tenured, so they contribute to the full GC.
With an HTTP cache in front, there is hardly anything left to be
cached, so there are lots of evictions. We get a query result cache
hit rate around 0.12.

At 10%, have you considered just not using the cache? Is that worth all
the extra work? Or are you not paying as much as your losing in GC/cache
time?
