hello,
Gateway delay p99 is much higher than other indicators
This is the result of my pressure test using wrk
My routing configuration is

@zhixiang0608 Have you ever tried to benchmark the upstream directly? It's unknown whether the long tail requests are due to upstream or APISIX itself.

ther routing delays are normal, only this one，using this formula, I think it has nothing to do with service
apisix latency = latency - upstream_reponse_time

can you use [openresty-xray](https://openresty.com/en/xray/) to test this route? It's really weird, and it's really weird to remove prometheus and use wrk2.

1. from case 1.1 and case 1.2, it is related to the regular configuration of the proxy-rewrite plugin
2. from case 1.1 and case 2.1, it is related to apisix version
but this does not explain the 53 ms delay.
Things you need to be sure of.
1. whether `/zymk-getuserinfo-api/` is the only route that has this problem, and if so, then it may be related to the upstream of this route.
2. remove the prometheus and proxy-rewrite plugins from the `/zymk-getuserinfo-api/` route separately to determine if it is an APISIX 2.6 issue or a plugin issue.

BTW, do not use wrk to do benchmark, see why:https://www.apiseven.com/zh/blog/analysis-of-inaccurate-distribution-of-wrk-latency, and disable the prometheus plugin, just use wrk2 to do:https://github.com/giltene/wrk2

You are saying that some requests are skipped `apisix_latency = apisix_latency - upstream_latency`? Or maybe some requests don't have `upstream_response_time`？
Let me think, what is the timeout set upstream?
I'm wondering if it's possible that the upstream response timeout is causing these requests to close.

from case 1.1 and case 1.2, it is related to the regular configuration of the proxy-rewrite plugin
from case 1.2 and case 2.2, it is related to apisix version
but this does not explain the 59 ms delay.
Things you need to be sure of.
1. whether `/zymk-getuserinfo-api/` is the only route that has this problem, and if so, then it may be related to the upstream of this route.
2. remove the prometheus and proxy-rewrite plugins from the `/zymk-getuserinfo-api/` route separately to determine if it is an APISIX 2.6 issue or a plugin issue.
