just wondering I did a benchmark within the pg of my gce build to find out what kind of processor its using because its clearly out performing mine on my regular local pg machine.
i set the automated settings on the gce builder within pg to a 4core 8gb machine.
while netdata shows the gce cpu during heavy downloading unpacking and repairing maintains about 60-70% cpu usage my io wait is virtually 1-5% . everything runs super smooth and instant.

where as on my local machine my cpu hovers around 40% cpu and 10-15 % io wait right up until sabnzbd needs to verify or repair then it sky rockets to 100% cpu and 70% io wait

granted to be fair my local machine has an hdd and the gce has the nvme drive. ( I will recktify this by later adding a ssd to the local machine ) but its hard to believe just the hard disk makes that much of a difference. Im trying to find out if the gces cpu is better and how much better. I was hoping to get a passmark or something


my real local pg machine-
CPU model : Intel(R) Xeon(R) CPU E3-1225 v5 @ 3.30GHz
Number of cores : 4
CPU frequency : 1487.128 MHz


gce vm-
CPU model : Intel(R) Xeon(R) CPU @ 2.30GHz
Number of cores : 4
CPU frequency : 2300.000 MHz

CPU Frequency and Drive speed are probably the 2 most important factors in what you have described, and it looks like GCE is crushing your @ home specs in both of these areas. It's hard to believe but the effeciency, speed and vastly better random write/read performance of NVME SSD's is almost definitely why you're noticing such a big difference.

Forgive my ignorance but why is my frequency showing as less of a number than my clock speed where as the vm computer frequency and clock are identical. Is something wrong or is that normal
