Another option you can try is adjusting the Config File Cache size. Go to Settings → Troubleshooting, then change the cache size from Automatic to 3 GB or 4 GB, depending on the memory available on your server.
This won’t reduce the initial load time, but it allows more objects to be stored in memory. If many users are logged in at the same time, this can help improve performance since the system won’t need to read from disk as often.
Keep in mind this is just a suggestion and not a guaranteed fix, but it’s worth testing. Please let me know if it makes a difference.
