Enabling Sleuth slows requests down (a lot)
问题 I use Spring Cloud Feign and Sleuth with a Zipkin server. My problem is that when I enable Sleuth, then any simple request takes at least 600ms. Note that for tests purposes, I've set the sampler percentage of Sleuth at 1. Can I do something to improve that? Here some log of a request which takes 25ms without Sleuth and 700ms with Sleuth. (user calls /teams which calls /cities): 13:46:46.064 [http-nio-8080-exec-3] DEBUG o.s.c.s.instrument.web.TraceFilter - Received a request to uri [/teams]
