I am looking at getting Silk Performer and I have a demo scheduled for later this week. I am looking to see if there were any suggestions on questions to put to the folks giving the demo.

We are a small company (<100 employees). We are a SaaS/Web Site company with several site we maintain. Our concern is how we well our current setup will handle the load as we continue to grow. I think we only need 50 to 100 VUs to start and we can 'rent' more for spike testing as needed.

We are looking at a few products, but Silk is the only one that is not open-source. I would prefer to go with something like this since I know they will be around in the future. But, costs are a consideration.

Any suggested questions would be great.

Anyone has any opinions, I would love to hear that as well.
