I'm using Google Cloud, 2 CPU and 4 GB memory. CentOS 8 with cyberpanel and openlitespeed.
Installed clean wordpress from cyberpanel. Install and setup litespeed cache with redis running.
Now, here's the fun part...
Tested my homepage (clean wordpress theme) using loader.io with 10k traffic in 1 minutes. No issue. error rate was very low with 0.1%.
Create a new page. Just a test page. Fill with title and a bit text content. Send 10k traffic in 1 minutes. Failed in the process.
Send 4k traffic in 1 minutes. Failed in the process. Error rate is more than 56%.
Send 2k traffic in 1 minutes. Process runs till the end. Error rate is 12%.
Is this normal? Is there any settings that I need to change from the default ones to make it better?
But why does it happen in the internal page and no issue with the homepage? I even tried to change the server from google cloud to digital ocean and vultr. All are giving the same results.
Anyone can help figuring this out? Many thanks.
