When you changed the database, you should close the old stream and open a new stream according to the new database.

What's your use case? Seems you want single match in each stream block, not the whole stream?

I don't think we can perfectly handle this kind of behavior at the moment, unless you scan each line separately. We may think about how to support this feature in...

Hi, your result under AVX512 shows nearly 15% performance drop against SSSE3, which seems too much to me. Actually this case only touched the large scale multi-literal matching part in...

I believe we're using the same code, rule and corpus, because the bytecode CRC, corpus size and match rate are all the same, my result under AVX512 is as follows:...

OK, so the problem should be elsewhere.

> @fatchanghao I will be very grateful if you could synchronize the cpu, gcc and other related information you used for testing, I want to verify if it is the...

I found a Intel(R) Xeon(R) Gold 6140 CPU @ 2.30GHz, gcc 7.4.0, Ubuntu 18.04. Benchmark on this platform showed AVX512 has 1.8% performance drop.

Have you tried deleting 6~10000 as they're all duplicated expressions?

will you give more detail about your issue, like the platform you're running, how you build, what's the error message?
