Hey, thanks for point out latency, I haven't look at them deeply. Here is
how http-kit compare to Nginx when concurrency is 96:
Server Software: http-kit
Server Hostname: 127.0.0.1
Server Port: 8087
Document Path: /
Document Length: 1163 bytes
Concurrency Level: 96
Time taken for tests: 2.858 seconds
Complete requests: 120000
Failed requests: 0
Write errors: 0
Keep-Alive requests: 120000
Total transferred: 156960000 bytes
HTML transferred: 139560000 bytes
Requests per second: 41981.59 [#/sec] (mean)
Time per request: 2.287 [ms] (mean)
Time per request: 0.024 [ms] (mean, across all concurrent requests)
Transfer rate: 53624.92 [Kbytes/sec] received
Connection Times (ms)
min mean[+/-sd] median max
Connect: 0 0 0.1 0 4
Processing: 1 2 0.7 2 7
Waiting: 1 2 0.7 2 7
Total: 1 2 0.7 2 7
*Percentage of the requests served within a certain time (ms)*

* 75% 2*
* 80% 2*
* 90% 3*
* 95% 4*
* 98% 5*
* 99% 5*
* 100% 7 (longest request) *

btw, I am the author of http-kit <https://github.com/shenfeng/http-kit>:
https://github.com/shenfeng/http-kit . http-kit was written from scratch
for performance. Clojure web application can be very fast, as fast as
Nginx can do. Clojure web application can handle high concurrency as Nginx
can do too.
