4 years ago Show your info of config.ini.
Different scenarios require different configuration parameters to achieve optimal performance
And vs officical Redis, the performance of F-Stack can be improved by up to 20-30% use one instance.

3 years ago You can try to adjust the value of some parameters, such as pkt_tx_delay or net.inet.tcp.delayed_ack etc. In different test scenarios, different parameter values will have different performance.
For example, pkt_tx_delay set to 50 or 100 us, contribute to the performance improvement of batch requests.

Thanks, by reducing pkt_tx_delay, it runs much more faster.
Hello,
I have simple setup to test the performance of Redis with f-stack (v1.20). Two PCs equipped with one 10 GbE NIC (Intel X540-AT2) are directly connected by an Ethernet cable.
The PC B (use generic linux network stack) runs the command to test the two servers' performance
However, I got the results
The f-stack Redis' performance is similar to official Redis. Is this expected? Or, is there any setting incorrect?
By the way, I also test the f-stack nginx and official nginx. f-stack nginx's performance is roughly three times better than official nginx.
Thans!
