哥，后面会有xctl吗？发现内置json一启动就占用将近80M内存，openwrt有点吃不消。

理论上不会这样，v2ray-core v4.32.1 也是不依赖 ctl，Xray-core v1.0.0 进一步吃了 ctl，多试几次看看。

哦~忘了说了，我的4.32.1是自编译有ctl的，如果用官方的也是会将近80M 。
VPS服务器x86平台，XEN \ KVM，debian9、10刚试了是正常的15-20M启动内存范围。
不知道是不是我路由器armv8 cpu架构的问题（内核5.4）。

等等看有无更多反馈，你可以先尝试编译精简版的 Xray

但若只在一个机器上有差异，就比较奇怪了

家里搞一个all in one，上面做网关，你就不会在意这些细节了

看来这的确是个值得关注的问题

NG 一些 issue 可能是这个原因，似乎只有 arm64 存在这种问题

之后会研究对应的解决方案

嗯嗯，他说的那个是上图虚拟内存VIRT吧？就是v2ray向系统申请的虚拟内存（如果小机自身内存过小，虚拟内存没设置，就会启动不起来），虽然不会全用到，不过4800M将近4G的申请，感觉是不是有点大？我记得没爆出aead重放问题之前的v2ray版本，申请的虚拟内存好像是780M左右（不过这又是另个问题了）。 我现在的是RES实时内存，一启动就80M。可能确实是arm64的问题。下图帮你测了4.31.3，有ctl是正常的。另台arm64机器过几天到了在试试看吧。
