High Wait Time on 4GB Droplet
we are experiencing a very high waiting time on our website on a droplet with 4GB memory and 2CPUs. Our website is running on Wordpress and have tried different caching plugins but still facing an average of 2s for first byte. We've tried also doing a test on [loader.io](http://) to check load capabilities and average server response time.
What we had was a real disaster:
We checked 100 connections in 1 minute and saw the test fail after 20 seconds due to reached threshold errors, all the more the average response time was of 7985 ms!
We then checked with 15 connections in 1 minute and managed to run through the whole minute with an average time of 1314 ms, which is still not good at all.
Morever when occurring a request the page is not rendered at all*
Thanks in advance for the help!
