@thecancerus looks like you are using WordOps for that https://community.wordops.net/ is the right place to look for support.
Since EE v4, we strongly recommend using Redis for full page cache.
Still, I will give a wild shot based on your use of WPFC
cache.
You can try disabling the archive purge option (if its enabled)
@rahul286 thanks, we were using the purge archive settings. I will also explore the Redis cache and see how it goes.
Redis uses Lua so purging is very fast ➞ https://github.com/rtCamp/nginx-helper/blob/master/admin/class-predis-purger.php#L249-L258
You can uncheck archive checkboxes until you shift to redis-based full page cache.
We need to purge archives as well, so for now we have modified the plugin to insert the URLs in a queue instead of doing a real-time purge, then handled the purge using cron.
Checking the dev setup with Redis Cache, we already use Redis for other things, mostly we will also move to Redis cache from wpfc
cache.
I would suggest this fix. But the repository seems private, I can't commit. In my test case it speeds up Wordpress post saving from 9 seconds to 2 seconds.

WordPress/wordpress-develop#3022 should help with this.
Still same. Creating/editing when saving post it takes up to 10 seconds
I have set up the local development for the same using LocalWP. After installing the plugin, I have used the Redis Object Cache Plugin. When I Purge the Entire Cache from Nginx Helper Plugin it is not purging the specified keys in Redis. After debugging I found out that the prefix key generated and passed to LUA script is different than the one stored in Redis.
Key Prefix - new-page-cache
Key Prefix Passed from Code to LUA Script - new-page-cachehttpGETnginx-helper.local/*
So am I doing something wrong?
Anything on this
When editing a post with multiple tags and categories attached to it, it takes lots of time to update. Sometimes it can take more than a minute. When I investigated, I found that most of the time was taken in the purge requests ( anywhere between 500ms to 1.3seconds per request).
My Setup
WordPress 5.7, Nginx (based on WordOps), WPFC cache with PHP 7.4. Server: AWS t2.xlarge, OS ubuntu 20.04 Neingx helper plugin version 2.2.2
