Hi,
For large file - 9152309 bytes,136595 lines of 67 char each.
(/tmp/total_hash_all_env_log )
For grep 2.4.2 the commands below takes 0.55 seconds to find 45549 lines
For grep 2.5.1 the commands below takes 5 minutes and 47 seconds....!!!!
This test is running under Linux - RedHat 9.0 using the downloaded gz
files from your site.
Command :
time ./grep prd1dhi /tmp/total_hash_all_env_log | wc -l
Thought you should know....
