@icoco This is done by Golang itself. It's based on your number of CPU cores.

You can try setting runtime.GOMAXPROCS(num) before starting Fiber.

@ReneWerner87 @efectn Should we add a config option for this? Just to make it more user friendly.

[icoco]

thanks for reply, I did it but seem not effect,

[ReneWerner87]

by default, gofiber uses only 1 thread for the server start
if the prefork feature is used and activated, the number of available threads is automatically determined and used optimally
therefore no specification of the threads is necessary
simply use or omit the prefork feature

[icoco]

not sure which step wrong, this looks is simply but confuse really

[ReneWerner87]

if you want to use multiple threads for the server, then you should also use the prefork feature
i.e. Prefork must be set to true

[ReneWerner87]

and please do not set MAXPROCS

[gaby]

Yeah, what are you trying to accomplish? @icoco

If max performance: enable prefork

[icoco]

I want reduce , only one work thread is ok, because it just for test purpose

[ReneWerner87]

by default without prefork it is only 1 thread or process that is used
either you have not terminated the other processes correctly or your local goland is out of order

[ReneWerner87]

in your pictures, the paths of the file you have customized and the file you have started do not match, please check if you have customized the correct file and removed the prefork
