有没有试过腾讯的 TCPA 的?看描述说比 BBR 要屌

[d0m2o08]

看测试结果比 BBR 要屌啊，准备有时间找个小鸡尝试下

[kernel]

这个是内网的吧，然而你看看另外的图，国外的高延迟的，和 BBR 一致，所以实际对 FG 没有用

[mengzhuo]

稍微看了一下，好像是针对大文件下载
不过内网也没啥关于这个的介绍（手动狗头

[d0m2o08]

@kernel 搜了下别人的对比视频，速度介于 bbr 和魔改 bbr 之间，效果比 bbr 略好

[Kinnice]

TCPA 小文件要强些，默认加速 80/8080 端口，专门建网站的推荐。

[liuxu]

ethtool -K ntuple-filters on 改不了，fixed 了。。

[ioiioi]

fixed 说明是网卡不支持该特性。

[liuxu]

@ioiioi 我手里的小鸡都不支持，连腾讯自家的 CVM 也不行

[sdrzlyz]

kernel-3.10.0-693.5.2。。。内核有点老啊，准备拿 gcp 做个测试

[hilbertz]

大公司就是喜欢搞各种 kpi 轮子项目，实际和 bbr 不会有什么区别的

[labnotok]

敢用？

[testcaoy7]

试了下，FQ 还是 BBR 更好

[lscho]

已经用上了。阿里河腾讯的机器都能装。。。。效果感觉不出来

[sdrzlyz]

1、内核版本比系统自带的要老，install 时需追加 --force 参数

2、uname -r
tcpa - 3.10.0-693.5.2.tcpa06.tl2
bbr - 5.0.1-1.el7.elrepo.x86_64

3、
iperf3 -c $TCPA_IP -p 443 -i 1 -t 10 -w 100K
iperf3 -c $BBR_IP -p 443 -i 1 -t 10 -w 100K


4、拿阿里云张家口节点做测试

https://lscho.com 测试网站。。。不知道怎么测试

[ryd994]

[imswing]

还是选择锐速

[testcaoy7]

要是这玩意哪天能整合进 Linux 内核就好了

[junjieyuanxiling]

[Katrol]

听说是不开源、专属内核、身份绑定
