- By default, tarfile library do gzip compression at 9 level - Anything above 5 or 6 can take significant resource and time - Based on tests, result of compression of 10 frappe apps around 430MB - With compression level 5, it takes ~8.5s and compressed file size 239MB - With compress level 9, it takes ~13.5s and compressed file size 235MB So, we are not getting too much benefit from using compression level 9
Usually in macos, we have different uid/gid than any linux system So, in development, it was causing issue. That's why the permission modification was added - frappe#1925 But, in prod it's not required. So, we can just modify permission, when developer mode is enabled

@tanmoysrt you might wanna add all existing violations to cspell whitelist in one shot, else it will become a continuous annoyance and won't help much. |
Added those words in whitelist. |

By default, tarfile library in python do gzip compression at level 9 (ref).
tarorgzipcli use compress level 6 by default (ref).Anything above 5 or 6 compression level can take significant resource and time.
Locally, I have cloned 10 frappe apps (430MB) to compress with different gzip level using tarfile.
