mount功能测试

目前已知的几个现象如下：

wdb[/var/run/usbmuxd] <--> haproxy (:27015 <-> /var/run/usbmuxd.system)
1. tidevice reboot异常，必现
2. tidevice developer失败，必现
3. go-ios image auto失败，必现
4. ideviceimagemounter成功
haproxy (/var/run/usbmuxd <-> /var/run/usbmuxd.system)
1. tidevice reboot成功
2. tidevice developer成功，几乎总能成功
3. go-ios image auto，失败，高概率，使用ctrl-c终止后，重试1~5次差不多总能成功
gocat <--> haproxy
1. tidevice reboot成功
2. tidevice developer成功，共测试五组，全部成功
3. go-ios image auto失败
  - [1] ctrl-c尝试第二次成功
  - [2] ctrl-c尝试第四次成功

# 启动haproxy，(:27015 <-> /var/run/usbmuxd.bk)

# 启动gocat
sudo ./gocat tcp-to-unix --src 0.0.0.0:27015 --dst /var/run/usbmuxd
sudo chmod 777 /var/run/usbmuxd

windows测试

首先下载windows版本itunes，也可以微盘获取：udt版本发布-ios resources目录下
测试环境，个人开发机windows server2019

27015端口监听ip确认

测试目标：启动Apple usbmuxd服务后，检测其监听27015端口的网址是127.0.0.1还是0:0:0:0。确认当用户使用windows接入iOS设备时，是否需要Haproxy

macOS/Linux上检测端口可使用 lsof -i tcp:27015，windows上对等方法

PS C:\Users\Administrator> NETSTAT.EXE -ant | findstr 27015
  TCP    127.0.0.1:27015        0.0.0.0:0              LISTENING       InHost

使用go-nc测试全局27016端口，然后使用上述命令检查端口状态，可见监听ip为0.0.0.0

PS C:\Users\Administrator> NETSTAT.EXE -ant | findstr 27016
  TCP    0.0.0.0:27016          0.0.0.0:0              LISTENING       InHost
  TCP    [::]:27016             [::]:0                 LISTENING       InHost

参考：https://stackoverflow.com/questions/15708/how-can-i-determine-whether-a-specific-file-is-open-in-windows

总结：

iTunes在window上监听的是localhost:27015端口，不具备局域网连接能力
如果使用windows接入iOS设备，并接入UDT，则需要Haproxy，且需要使用其他端口

mac <--> windows serevr局域网联合测试

由于HAproxy没有提供windows版本，手动编译需要mingw或者cygwin，较为麻烦；而realm（使用rust编写）提供了多个平台的windows包，因此在windows上使用realm替代Haproxy。

./realm -l 0.0.0.0:27016 -r 127.0.0.1:27015

然后在同一个局域网的mac电脑上启动wdb，并在其中测试各项功能

昨天的初步测试，macOS上出现的现象是：

几乎所有命令执行时间很长，如tidevice info，可达30S~1分钟

但奇怪的是，今天重启了几次电脑后该现象消失。后续仍需要留意

iperf性能测试

直接使用tidevice
iperf3: https://iperf.fr/iperf-download.php

$ ./iperf3 -c 127.0.0.1 -p 5201 -t 10
[ ID] Interval           Transfer     Bandwidth

[  4]   0.00-10.01  sec   302 MBytes   253 Mbits/sec                  receiver

平均速度为263/253Mbps

$ iperf3 -c 127.0.0.1 -p 5201 -t 10
[ ID] Interval           Transfer     Bitrate
[  5]   0.00-10.00  sec   185 MBytes   155 Mbits/sec                  sender
[  5]   0.00-10.04  sec   182 MBytes   152 Mbits/sec                  receiver

局域网转发以后，性能损失大约在40%， 155/263=58.93%， 152/253=60.07%

下午windows系统升级到win 10 22H2版本后，重新测试

windows原生效果

259/250 Mb/s (10s)
257/247 Mb/s (10s)
247/238 Mb/s (10s)
261/252 Mb/s (10s)
248/246 Mb/s (60s)

局域网转发一次后

132/131 M/bs (30s)
136/135
137/136

这次的损失在47~45%左右。
