I tried to scale Stellar Standalone to process 4000 tx per second.
I use AWS EC2 m4.large for Core, and Horizon. Also I use Postgres RDS for core and Horrizon, but I have only 560 tx per second. My instance reaches only 10% of CPU load. I had just 180 stable connections on the instance.
Can anyone please advise on best practices and how I can improve/maximize the performance?
