Dec 20, 2023 · Google recommends you aim for a response time lower than 200 milliseconds. A 100ms TTFB is ideal, and everything over 500ms is an issue. This time must be consistent for all users. It should not vary depending on the users’ geographical positions. Google classifies websites into three groups based on the speed score they achieve: Fast (90-100) Nov 16, 2023 · Comparing Internet Speed Tiers. Basic – 25-100 Mbps plans suitable for 1-2 users and light usage. Fast – 200-400 Mbps for 3-5 users and moderate to high usage. Ultra-fast – 500Mbps-1Gbps for households with many heavy users and devices. So at 250 Mbps, you are solidly in the upper range of fast speed tiers. May 5, 2016 · 200ms to 500ms seconds is a good range to start with for interface animations. Using this range as a guide, small UI animations — ones that involve smaller elements or small amounts of change — tend to be on the lower end in the 200ms to 300ms range. Larger motion that covers a lot of ground, or motion that uses complex bounce and elastic Use Gzip, a software application for file compression, to reduce the size of your CSS, HTML, and JavaScript files that are larger than 150 bytes. Do not use gzip on image files. Instead, compress these in a program like Photoshop where you can retain control over the quality of the image. See "Optimize images" below. Miles per hour to Millimeters per second Conversion Example. Task: Convert 250 miles per hour to millimeters per second (show work) Formula: mph x 447.04 = mm/s Calculations: 250 mph x 447.04 = 111,760 mm/s Result: 250 mph is equal to 111,760 mm/s. In addition to reaction time, it takes between 150-190 milliseconds from initiating the swing to making contact with the ball. You'll also need to know the distance from the pitcher to home plate, and the speed of a pitched ball. (Wiese, 2002, pp. 6-8; Adair, 2002, Chapter 3; Brody, 1987, pp. 145-147.)
