File access in mounted volumes extremely slow, CPU bound

I can confirm the slow FS performance.

Here’s my stats:

user@Native-Mac-FS/app$ time time dd if=/dev/zero of=speedtest bs=1024 count=100000
100000+0 records in
100000+0 records out
102400000 bytes transferred in 0.360199 secs (284287317 bytes/sec)
real    0m0.373s
user    0m0.022s
sys     0m0.288s

vs performance in the container:

root@660d6823b06f:/app$ time dd if=/dev/zero of=speedtest bs=1024 count=100000
100000+0 records in
100000+0 records out
102400000 bytes (102 MB) copied, 39.5285 s, 2.6 MB/s
real    0m39.538s
user    0m0.200s
sys     0m1.990s

I can also +1 slow FS performance is preventing us from deploying Docker in a bigger way for our development environments.
