Why is my new scaled droplet (8GB RAM - 4 vCPUs) is 4 times slower than the old one?

Last Friday, August 11th 2018, I scaled my VPS for my website. As I started to receive more and more requests for LRC Maker and Downloads (Lyrics files), my CPU crossed 100% multiple times, and was averaging 80%.

The Apache server in the old VPS 4GB RAM and 2vCPUs used to load the Main Page in 200-250ms, now the new one with 8GB RAM and 4cCPUs is loading it in 900-1200ms. Just some minutes before the scale, the speed was still excellent. Now all the pages are taking 4x more times than before, I even started to loose some pageviews that kept until then increasing fastly.

I just try to update /etc/resolv.conf, without rebooting, but with no success. What could be behind such a slow performance?

Ubuntu 14.04, Apache 2.4, PHP 5.6, MySQL 5.5.9, Laravel 5.0, Same Codes as before…

Hello friend!

Sorry to hear about the trouble this is giving you. The source of the slowdown could be anywhere, and finding it is not always an easy task. It could be anything from a package upgrade going live after the reboot that came along with the resize, to a problem with our hypervisor. To rule out external factors, I’ve given you some credit to cover the cost of creating a snapshot and spinning up a new droplet. This will help you to determine whether the problem is most likely inside of your operating system or outside of your droplet.

If it is determined to be external, open a ticket with our support team and let us get that documented on your account as we work through it (I saw no clear evidence that it is, but that is not always conclusive). If it is determined to be internal, you’re going to need to troubleshoot every layer of your software stack until you find where it is slowing down. That may require watching MySQL queries, running strace on a PHP process, and perhaps even simple use of things like

Kind Regards, Jarland

Everything is good now. That means the Physical Server or the Sub-Network hosting the scaled VPS was really slow, even when taking a snapshot!

Now my production server response very fast again.


4 hours in 5 more minutes till a SNAPSHOT is creating. Now is there a way to cancel the SNAPSHOT process?

I will do a fresh VPS setup instead another day, backup the database and restore it in the new VPS, move the Static files to new VPS, and send request to it with Proxy Server.
