Michael Dürig commented on OAK-4936:
------------------------------------
Running with above patch for the LIRS cache gives me number comparable to those
with the Guava cache.
[~tmueller], the LIRS cache is used in other places as well and I cannot assess
how this patch will affect its performance there. What would you recommend for
going forward?
