Targeting website to reduce page load speed - a new negative SEO tactic?

My website is being hammered by scripts and bots setup to download our largest files and images for no reason. Im talking large amounts of data, rotating ips, clear intent to be deceptive. Most of the ips are based out of areas of the world known for pretty bad practices.

Even though we have been around for over a decade and are a fairly well known property this has only started in the last couple months.

My question is simple.

Do you think people/companies would target your website now to overload/tax the server as much as possible to reduce your servers response times?

This would then reduce your overall site load times and possibly hurt your rankings.

Im not talking about rogue scraper scripts out of russia or hack tools out of romania. Im talking about rotating user agents and ips slamming the biggest files on your server tens of thousands of time per hour. Not enough to take the site down but enough to degrade performance.

I have found concrete evidence of this in my logs lately. Anyone else?

Some certainly might try this kind of disruption tactic against their competition. But since site speed is only a very minor factor right now, their energy is quite misplaced -- unless it severely impacts your server's ability to respond. And then, it's more of a denial of service attack than just an attempt to hurt page speed.

add a 5 second pause before any download begins, add another for any multiple attempts from the same IP, and add a limit to the number of downloads allowed per day (per IP). A number beyond what the average user would try works, you're just looking to cap the possible download rate.

There are two distinct targets now

1. What is the actual download speed from the site.
2. What does Google see from Toolbar (and show in WMT).

Both the attack (downloading large files repeatedly) and proposed defence (limit number of downloads) are associated with actual download speed (1). Neither the attack nor protection would be effective against the toolbar foolery.
