Hello everyone,

I have a question regarding the performance of drools. The scenario is this.I have a huge file. This file is produced by one of the 30 devices we have in the lab.We have to figure out which of the device produced this file . Each of the device has a its own "signature line", by which I can distinguish each of the devices. So, previously what I was doing was, reading each line in the file,checking if it is the "signature line" for that device.All this is ordered. So if is my correct device is 30th, I have to read this huge file 30 times,thus wasting a lot of time

I thought drools might come in handy in this scenario. So I have the rules, which basically reads a line in the file and asserts into the memory. Each time a new line is asserted into the memory,the rules for all of the remaining 30 devices, check if it is its signature line. If so, i have found out my device and clear the agenda.

But unfortunately i find that parsing the file 30 times id giving me a better performance then using the drools. Is there something I am missing
