`ffprobe` is 12 times slower than `metaflac`. How to speed up `ffprobe`?

Question

On a small FLAC folder of 1593 files, ffprobe takes over 12 times longer to run than metaflac. How to speed up the single-threaded performance of ffprobe?

I tried to tell ffprobe to do the same and print only the VORBIS_COMMENT or TAG field by running ffprobe -show_entries format_tags .., but this unfortunately doesn't improve the performance.

This script searches for possible URLs:

1.ffprobe:

$ time find . -type f -iname "*.flac" -print0 | while read -d $'\0' FILENAME; do
    INFOS=$(ffprobe -hide_banner "$FILENAME" 2>&1)
    URL=$("$INFOS"|& grep -i 'http\|www')
    if [ "$URL" != "" ]; then
        echo -e "$FILENAME\t$URL"
    fi
done | column -t -s $'\t'

2.metaflac:

(only this line is different:)

...
    INFOS=$(metaflac --list --block-type=VORBIS_COMMENT "$FILENAME" 2>&1)
...

Benchmarks:

The CPU is a Ryzen 5600X and the files are located on an external 850 EVO 1TB SSD.

Single-threaded benchmarks:

	$ time find ..
metaflac	real 0m2,579s
mediainfo	real 0m14,222s
ffprobe	real 0m32,379s
exiftool	real 1m21,881s

Edit To speed things up I modified my code to run in parallel:

getURLs() {
    FILENAME=$1
    URL=$(mediainfo "$FILENAME" 2>&1 | grep -i 'http\|www')
    if [ "$URL" != "" ]; then
        echo -e "$FILENAME\t$URL"
    fi
}

find . -type f -iname "*.flac" -print0 | while read -d $'\0' FILENAME; do
    getURLs "$FILENAME" &
done | column -t -s $'\t'

wait

This parallelized script version utilizes my 5600X CPU fully and the performance seems to be CPU-bound:

Multi-threaded benchmarks:

	$ time find ..
metaflac	real 0m0,695s
mediainfo	real 0m2,109s
ffprobe	real 0m4,844s

I'm asking for a single-threaded speed improvement of ffprobe, so I won't mark this as a solution, though it's a nice speed improvement indeed.
