Apply patch using composer-patches: https://www.classyllama.com/blog/create-apply-patches-magento-2#applying_patches

I prefer to apply changes like this as a patch, as if the underlying code ever changes, the patch will fail to apply and you can remedy the issue.

Overview

I ran some tests to determine the speed impact of removing unnecessary third-party extensions, per this article: https://www.integer-net.com/make-magento-2-small-again/ The TL;DR is that pages loaded about 10% faster (with full_page and block_html disabled) with the unnecessary extensions removed.

Extensions I removed:

"replace": {
        "magento/module-dhl": "*",
        "magento/module-fedex": "*",

Overview

This applies to Magento 2.3+.

If you have your crontab configured to run the bin/magento cron:run command using flock, you should either:

• Remove flock, since it's technically not necessary as of Magento 2.3.2
• Pass the -o command to flock, as this will prevent the indefinitely running bin/magento queue:consumers:start processes spawned by bin/magento cron:run from holding a lock when they shouldn't be.
