During my setup of benchmarking I run a quick test-sysbench script to ensure my configuration is right before running an hour+ duration test.
When pointing to a Readyset cache where I have cached the 5 queries used in the sysbench test, but I have not run any execution of the SQL, throughput went up 10x in 5 seconds.
$ sysbench --config-file=readyset.cnf --report-interval=1 --histogram=1 --threads=4 core.lua --type=title run
