This is not an individual ping from a single asset. If I click on assets to the right of Dashboard, then narrow the list down with filters to all PCs that start with HS-102, which returns 30, then I hit ping assets on the left the entire site slows to a crawl.
If you cannot reproduce this, I can take a screen cast video.
Also, this doesn't happen any other time. I could deploy a package to 30 computers and the site is fine.
