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? 

> Too many segment cache misses

> Running the {{ConcurrentWriteTest}} benchmark and monitoring the hits and 
> misses of the segment cache (LIRS), I noticed that some segments are loaded 
> over and over again (up to 3000 times).
