RE: Strange resource Content Download pattern
I think we got it thanks to you mentioning "CWND" Smile

So every time we run Linux kernel updates we would also run the following command:

/sbin/ip route change default via dev eth0 initcwnd 10

The thinking was that after we run kernel updates we would need to disable TCP slow start again. However, as it turns out TCP slow start must be disabled again after every server reboot. So every time we would reboot the server TCP slow start would get enabled again and our download times would go up.
