Tinyfecvpn x86 client CPU 占用100%

环境： Windows 10 64bit+ Virtual Box v6.0.14 +Openwrt (intel 32bit)--v18.06.5 Tinyfec版本：intel 32位版本，git version: 79d5e4dee8 build date: Aug 20 2018 12:20:44 使用top发现 tinyfecvpn cpu占用100%，cpu占用和流量关系不大，静默40-50kbps或看测速iperf3跑满时，cpu都是100%。 CPU: 62% usr 37% sys 0% nic 0% idle 0% io 0% irq 0% sirq Load average: 1.02 1.01 1.00 2/49 4033 PID PPID USER STAT VSZ %VSZ %CPU COMMAND 1755 1 root R 18092 7% 100% /usr/tinyfecvpn/tinyvpn_x86 -c -r serverip:serverport -f 10:10 --sub-net 10.222.20.0 --tun-dev tun100 --keep-reconnect -k password

使用strace -p tinyfecPID ,日志如下，不停的访问/etc/localtime，从ubuntu复制了zoneinfo文件夹至 openwrt的/usr/share目录下，并将Shanghai链接到/etc/localtime ls -ali localtime，重启后，tinyfec仍占用CPU 100%， openwrt WEB页面时区也设置成了上海。 142 lrwxrwxrwx 1 root root 33 Dec 9 19:23 localtime -> /usr/share/zoneinfo/Asia/Shanghai
