Hi Rajenda, That’s odd. We (the Hyperscan team) regularly benchmark much larger signature sets, and we certainly see the correct expression count reported. Are you using Hyperscan 4.4.1? (the current release?) Can you show us the command line that you’re invoking hsbench with? If you’re comfortable sharing the patterns you’re having trouble with, feel free to email them to me off-list and I can take a look here.

I didnt received any error, but expression count it is showing as 6000 (6k). Is there any limit on expression count. Thanks
