我目前正在尝试在AWS上部署Varnish。 此清漆旨在缓存来自S3的1个文件（只有一个文件，小于10kb），命中率为10k + requests / s
我已经在m4.large实例（2vCPU / 8Gb Ram）上部署了我的服务器。 我已经从Jmeter集群启动了性能测试，但我无法传递3.5k req / s，而且它看起来有点低。
当我检查我的系统指标时，我找不到任何瓶颈（CPU / Ram / IOPS / Network）。
我的清漆命令行：
/usr/sbin/varnishd -a :6081 -f /etc/varnish/default.vcl -T 127.0.0.1:6082 -t 86400 -u varnish -g varnish -S /etc/varnish/secret -s malloc,1G -p idle_send_timeout=0 -p thread_pool_min=500 -p timeout_linger=100000 -p thread_pool_add_delay=2 -P /var/run/varnish.pid
操作系统：AWS AMI - 2017.09.1
清漆版本：varnishd（清漆-4.0.5修订版07eff4c29）

您是否知道我如何调整清漆以获得更好的吞吐量？
