I say go ahead and use local state as a performance boost, so long as you’re fine to have that state wiped out at any moment. Systems such as FaRM and KV-Direct focus on improving the performance of PUT/GET operations, but don’t address the authors’ marshalling and overread concerns. Who knew! ;).

This post addresses both questions to illustrate exactly why HammerDB is written in Tcl and why using Python to benchmark a database can result in poor performance and misleading results. As our results show the more threads we add the worse the performance gets due to this GIL synchronization. Surely any language will do? wait: 0.0
