Bug Report

1. What did you do?

This is a nit, and probably not a P2, but it looked closest based on the classification system.

The bug #103 looks like it might not have been fixed properly. When I run tiup update --nightly --all, I see:

download https://tiup-mirrors.pingcap.com/pd-nightly-linux-amd64.tar.gz 30.52 MiB / 30.52 MiB 99.97% 6.79 MiB p/s                                           ..

My question is, why is p/s required here?

2. What did you expect to see?

It might be nice to format as follows:

[99.97%] https://tiup-mirrors.pingcap.com/pd-nightly-linux-amd64.tar.gz [30.52 MiB / 30.52 MiB] [6.79 MiB/s]                                           
..

This is useful because the percentage can be seen first (because the length of a URL is variable, it makes it hard on the eye to read anything on the right hand side).

3. What did you see instead?

download https://tiup-mirrors.pingcap.com/pd-nightly-linux-amd64.tar.gz 30.52 MiB / 30.52 MiB 99.97% 6.79 MiB p/s                                           ..

4. What version of TiDB are you using? (tidb-server -V or run select tidb_version(); on TiDB)

I have the latest:

wwar@ivory:~$ tiup update --self
download https://tiup-mirrors.pingcap.com/tiup-linux-amd64.tar.gz?v=1587266734335088527 3.31 MiB / 3.34 MiB 99.08% 4.76 MiB p/s

I am interested in this and i realy do something.

It look like this:

[100.00%] https://tiup-mirrors.pingcap.com/tiup-v1.0.9-linux-amd64.tar.gz [4.32 MiB / 4.32 MiB]  [12.74 MiB p/s]

I have no idea of change MiB p/s to MiB/s , so i have created issue in [Question] How can i use speed about MiB/s and not p/s .

If i missed something, remind me please!
