I've been running some tests against with a virtual instance of Astaro on Hyper-V 3 (2012) with the synthetic adapter that is not at all lacking for resources (it only show 1-5% CPU at any time and 30-40% memory usage). It has been allocated 2 vcores and 2 gigs of RAM. The box is connected to a gigabit Ethernet internet connection and I've been getting some odd results when trying to download random test files.
If I have snort 100% disabled (red X in IPS) I am getting on average 100-150Mbps download, yet as soon as I enable snort, even with NO rules enabled the transfer slows down to 6-10Mbps. I've tested this several times, even removing the network card that I am testing behind from the list enabled for IPS and still have the same result if the IPS is enabled (rules or no rules). I am getting no IPS drops/hits during this process, just the extreme change in speed.
There's no other activity on the network when I'm testing.
Is there something that I can tweak here? I'm guessing this isn't the expected behavior.
Thanks,
Keith
