Hi,
Massive pattern list handling with -E format seems very
slow, since grep 2.28.
Conversion from -E format to -F format may have problem
about performance.
When the processing time is measured by the script below,
the result isobviously different between 2.28 and 2.27.
#!/bin/bash
export
Hi,
I immediately tried the attached patch, and was able
to confirmthat grep perfomance is improved.
Our work to find thousands of patterns in a file with
tens of thousand lines is going extremely smoothly.
I'm glad for your quick response.
Thank you.
