Hi, I am new to regex and now I am trying to test the performance of the two algorithms in PCRE-7.8 by matching a large number of packets with a set of rules. I have some regular expressions from Snort but also need a large size of data (say 1 GB) with packets from 1KB to 1MB. Where can I find a handy tool to generate these data? Currently, I can only pass one pattern to match one string at a time in PCRE. Once I have these data, how can I pass all these packets and the regular expressions from Snort to the pcre? Is it possible to pass one file contains data and another file contains regular expressions to pcre? Thanks!
