[CLJS-499] Reassess ObjectMap vs. PersistentArrayMap Created: 25/Apr/13 Updated: 27/Jul/13 Resolved: 20/May/13
Here are some benchmarks after performance improvements have been applied to PersistentArrayMap in master:
For the smallest sizes PAMs are nearly identical in performance to OMs, as we start nearing the PHM threshold PAMs are nearly 2X faster on WebKit Nightly, and nearly 3X faster on the latest Chrome. Only Firefox Nightly lags behind for lookup times at larger sizes.
Again we see nearly identical (or much better) performance at small sizes and much better performance for PAMs as we approach the PHM threshold.

When I try to run the jsprefs I get "ReferenceError: cljs_perf is not defined."
