Hello guys,

How to improve Google compute instance perforamance. My instance is very slow. Please tell me Asap.

At First, could you please explain a little bit that what type of Google compute instance performance issues are you referring? as VM instance can be slow for different reasons. e.g: Disk performance, Network performance, CPU performance. If you inquiry related to the network performance of your VM instances then, I would recommend testing networking performance is important to improve your environment. However, the outbound or egress traffic from a virtual machine is subject to maximum network egress throughput caps. These caps are dependent on the number of vCPUs that a virtual machine instance has. Each core is subject to a 2 Gbits/second (Gbps) cap for peak performance. Each additional core increases the network cap, up to a theoretical maximum of 16 Gbps for each virtual machine.

In other words, the more virtual CPUs in a guest, the more networking throughput you get. You can see this yourself by setting up a bunch of instance types, and logging their IPerf performance. if you still believe that your instance is experiencing network performance issues, I suggest you to perform some tests by using iperf.

If your inquiry referring any other performance (e.g: Disk , CPU) then please explain which one you are referring.
