 ============
 
 Bitcoin Core has an internal benchmarking framework, with benchmarks
-for cryptographic algorithms (e.g. SHA1, SHA256, SHA512, RIPEMD160), as well as the rolling bloom filter.

+thread queue, wallet balance.
 
 Running
 ---------------------
+
+For benchmarks purposes you only need to compile `bitcoin_bench`. Beware of configuring without `--enable-debug` as this would impact
+benchmarking by unlatching log printers and lock analysis.

 Help
 ---------------------
-`-?` will print a list of options and exit:
 
-    src/bench/bench_bitcoin -?
+    src/bench/bench_bitcoin --help
+
+To print options like scaling factor or per-benchmark filter.
 
 Notes
 ---------------------
 More benchmarks are needed for, in no particular order:
 - Script Validation
-- CCoinDBView caching
 - Coins database
 - Memory pool
-- Wallet coin selection
+- Cuckoo Cache
+- P2P throughput
