E750 has a high cpu utilization

Routers

Hi, I just purchased a mudi E750v2, with EM060k modem. I noticed the cpu utilization is about 1.2 when there is only one wifi client connected, and almost no traffic. I saw the following lines at top. There is no pid with high cpu usage. Not sure why the overall load is this high.

Mem: 90112K used, 31076K free, 1396K shrd, 680K buff, 40180K cached
CPU: 15% usr 16% sys 0% nic 64% idle 0% io 0% irq 3% sirq
Load average: 1.23 1.31 1.26 1/95 10244
PID PPID USER STAT VSZ %VSZ %CPU COMMAND
2872 1 root S 5528 5% 3% /usr/bin/modem_AT -B 1-1.2
4060 3772 root S 8460 7% 1% nginx: worker process
3292 1 root S 3340 3% 1% /usr/bin/eco /usr/bin/mcu

Network data exchange (NIC) is consuming the CPU, but if there are no problems in the clients, this is supposed to be normal.

From the log, my understand is 15% usr, 0% nic, 64% idle. Somehow the load average is as high as 1.23.

Since the sys and usr are occupied CPU.
Anyway it is normally, as the E750 CPU does not very powerful, the load on the CPU will be relatively high. If the router works well, it can ignore.
