springboot version is 2.1.12.RELEASE. spring-cloud version is Greenwich.SR5. use eureka、zuul、feign、hystrix、ribbon、 i start one service to request another service, first time would take a long time, second time request is normal. if online service has concurrent request. when update the service and restart. in this moment, will cause request time out. even if config read-time-out、 content-time-out more longer. so how to resolve this situation
the attach can reproduces the problem by send http://127.0.0.1:8769/api-two/order/listUserByOrder twice

Hi, @ffyyhh995511, Greenwich release train is no longer supported. Please try against Hoxton.SR9 or 2020.0.0.M5.

Please try against Hoxton.SR9 or 2020.0.0.M5 and provide a sample with any of these release trains if it's still an issue.

hi @OlgaMaciaszek it does not work, i update to Hoxton.SR9 and springboot 2.3.5.RELEASE. it took about 1 second that i send http://127.0.0.1:8769/api-two/order/listUserByOrder first time. but it took only 34 ms second time
you can reproduces the problem by clone https://github.com/ffyyhh995511/enterprise-cloud.git you should start euraka 、service-one 、service-tow、 zuul in turn and send http://127.0.0.1:8769/api-two/order/listUserByOrder

HI @ffyyhh995511 @vinayak12
Do you see this param > ribbon.eager-load.enabled . I guess when you first time request coming then spring will load some bean and will cost some time , when second time request coming its will not happen.
pls try it.
@OlgaMaciaszek any thoughts?
thanks

@holy12345 yes. i config this param > ribbon.eager-load.enabled. but in concurrent request situation that will cause many requests be slow

Will be closing this issue since Hystrix and Ribbon are no longer supported by Spring Cloud.
