 * Google guava loading cache with variable size: org.opensha.sha.faultSurface.cache.MultiDistanceCache
 * Hybrid of both caches: org.opensha.sha.faultSurface.cache.HybridDistanceCache

+Caching style/parameters are configurable via the org.opensha.sha.faultSurface.cache.SurfaceCachingPolicy class, which can be configured via java properties. It defaults to using some form of multiple/hybrid cache for all surfaces except for Compound Surfaces, which default to the single cache.
 
 I then ran lots of tests at HPCC with many variations on these caching schemes. All tests were run on nodes with the exact same configuration:

 Sites are randomly distributed (tightly) around 35, -118. Tests were run with 1, 2, 4, and 8 threads (multiple runs of each configuration and times averaged).
 
+=== Plot Legend ===
+
+Each plot has a number of lines. Solid lines (force=false) mean that the surfaces used the given cache for all rupture surfaces except for CompoundSurfaces, which used the single location cache. Dashed lines (force=true) use the given cache for compound surfaces as well. If size == 1 and force=false, the single location cache is used for all surfaces (this is the previous surface caching behavior).
+
+The color is related to the cache size:
+* black = 1 (the solid black line represents the previous caching behavior, and is the line to beat)
+* blue = 2
+* green = 4
+* orange = 8
+* magenta = 12

 == First Results and Sensitivity to Java Version ==
+
+These are the initial results comparing the multi cache with the given size and a 1 hour access expiration with the single cache.
