I’m not sure I see how that translates to increased costs, unless you’re talking about power costs. Thanks for editing the text of your forum post, but your Twitter post still talks about Aerospike being slower on 4.5, which it isn’t.
You’re using community edition, the free version of Aerospike. What you can contribute is to open a good bug report in the
aerospike/aerospike-server repo. Please include your config and the spec of your hardware.
Also, when asking for help please follow up with feedback and requested information. I have personally helped you by answering your questions on stackoverflow, but you tend to leave your own issues hanging, without feedback and without selecting the correct answer. The idea is to not just get an answer for your specific issue, but for the Q&A to also be helpful to the wider community.
