Using bash on Emacs, procs-0.12.2 is very slow compared to procs-0.11.13.
Below is a Dockerfile for testing this phenomenon.

FROM rust:1.61 AS builder

WORKDIR /work
RUN git clone https://github.com/dalance/procs.git && \
    cd procs && \
    git checkout v0.11.13 && \
    cargo build --release && \
    mv target/release/procs /work/procs-0.11.13 && \
    git checkout v0.12.2 && \
    cargo build --release && \
    mv target/release/procs /work/procs-0.12.2

FROM ubuntu:20.04
COPY --from=builder /work/procs-0.11.13 /usr/local/bin/procs-0.11.13
COPY --from=builder /work/procs-0.12.2 /usr/local/bin/procs-0.12.2

ENV TZ=Asia/Tokyo
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone

WORKDIR /work
RUN apt-get update && \
    apt-get install -y --no-install-recommends emacs && \
    mkdir /root/.emacs.d && \
    echo '(setq inhibit-startup-message t)' > /root/.emacs.d/init.el

1. docker run this.
2. emacs -nw
3. (on Emacs) M-x shell (M-x is Alt + x)
4. (on Emacs) bash
5. (on Emacs) time procs-0.11.13 --pager disable
6. (on Emacs) time procs-0.12.2 --pager disable

This is the result.

Thanks!

This is because emacs doesn't support termnial background color query,
so procs wait until timeout.

I fixed it, and released v0.12.3.

Thank you for fixing it in an instant!
