IpV4 Address Counter

App calculates the number of unique IPv4 addresses in a given file and print the result.

Features:

• Processing large files
• Ready-to-work with simple CLI
• Supports goroutines for faster processing

Usage

Build project into binary:

make build-mac

Supports two modes of operation:

1. Without goroutines

./bin/counter -path="path_to_file"

2. With goroutines

./bin/counter -path="path_to_file" -allowParallel=true

Note: by default, the app will use the first mode. To use the second mode, you need to specify the -allowParallel flag.

Benchmarks

Tested on large file.

Without goroutines:

Unique ips:  1000000000
Total time: 8m39.046350542s
Alloc = 577 MiB TotalAlloc = 122578 MiB Sys = 1075 MiB  NumGC = 241

With goroutines (5 workers):

Unique ips:  1000000000
Total time: 4m34.130946167s
Alloc = 556 MiB TotalAlloc = 122582 MiB Sys = 1079 MiB  NumGC = 241
