AWS AMI performance issue?
AWS AMI performance issue?
Hi,
I've recently encounter some performance issue when I deploy AMI version of VestaCP 0.9.8-17 on Ubuntu 16
What I've done was setup Wordpress + Woocommerce on VestaCP 0.9.8-17 Ubuntu 16 in Region A, take AMI snapshot, then deploy to Region C, and run an ELB load balancer on top of it. So A is the original copy of the instance, and C is exact the same as A. I did change the host name and that's about it. and the local IP is served automatically from VPC DHCP server.
However do noticed that C is about 50% slower than A (1000ms vs 500ms), i am wondering if there's any other configuration change needs to be make after I launch C?
Thanks in advance :)

Re: AWS AMI performance issue?
And why so? (if servers specs looks identycal, right?)C is about 50% slower than A
top/htop say something? Problem with cpu/ram/IO ?
Re: AWS AMI performance issue?
Yeah, server spec is exactly the same, nothing with processing / resource, so I am suspected something need to be re-config after I launch the instance, e.g. something similar to v-update-sys-ip?skurudo wrote:And why so? (if servers specs looks identycal, right?)C is about 50% slower than A

Re: AWS AMI performance issue?
Network Latency or distance. Also you are using a load balancer? So your connection is going through the load balancer this has also it's latency.
Re: AWS AMI performance issue?
Yes it's going through LB, however if it's that then both service should have the same latency issue...tjebbeke wrote:Network Latency or distance. Also you are using a load balancer? So your connection is going through the load balancer this has also it's latency.
Re: AWS AMI performance issue?
LB - one latency - region A
LB - other latency - region C
One LB, two different latency, no?
Did you try ask some from AWS support about this?

Re: AWS AMI performance issue?
It turn out to be the network latency between web and other services (redis cache & db), web is in a different AZ than the two.
