For more than a year I have been using this program, which compresses traffic. Regardless of where I work and what the Internet is, 56 or 254, the program reduces traffic costs by an average of 30%. You can say that traffic is now worth a penny, but I will tell you that opening a page with 250 kb of text at a speed of 5.5 kb per second (at home) is better to spend 5-10 seconds than 1 minute.
Initially, the program was written in Java, now I found that there is a version, purely for Windows, that does not require it, which has a positive effect on the free RAM.
