Hi,
We are using ARR 2.5 for CDN purpose with 3 edge nodes & an origin server. We are using IIS Smooth Streaming.
When the server reaches 200+ mbps we see suddent burst of TCP conenctions(jumps from 200 conenctions to 500+ connections), the disk queue length go down to zero and everything stops for few seconds before the tcp connections go back to normal. I have tried all kinds of ARR settings and it's still the same.
Below are the necessary info regarding this issue:
Hard Drive Setting: 3 x 2 TB Sata with Software Raid 0
Memory: 72 GB (Almost all of it is shown as cached/Standby, leaving few MB as Free)
HDD disk queue length: On Average 15-25
I am attaching the Network & Disk tab image from resource monitor here.
