I have tried what you suggested. Granting "Developer Tools" access definitely FIXED THIS ISSUE for the specific application.

Here is the new result (I only run once for each case):

    ╒══════════╤═════════════╤═══════════════════════════╕
    │          │             │ +"Developer Tools" access │
    ╞══════════╪═════════════╪═══════════════════════════╡
    │ terminal │ 1.448/0.004 │ 0.016/0.004               │
    ├──────────┼─────────────┼───────────────────────────┤
    │ iTerm2   │ 1.240/0.006 │ 0.024/0.007               │
    ╘══════════╧═════════════╧═══════════════════════════╛

`1.448/0.004` means the first time it is `1.448 total`, and the second time it is `0.004 total`.

(It seems I have "good" VPN/internet connection condition at this time)
