You can use the StartupTimingQuery example query in the perfetto UI to find startup time. and matter fact, Macrobenchmark uses StartupTimingQuery for capturing startup time.

The old becomes the new.. and back to old again. If you have been working for a long time with perf you will stumble with clock_source and TSC. Great write up by @brendangregg https://t.co/ljbOzAa54r ...Been there as well. #Perftips #TSC_Clockres

@hai32136020 Hi π
You can improve the LCP metric preloading the main image ππΌ https://t.co/XzS60clanL
But the main problem, IMO, is the TTFB. The server has a very long response time. Take a look to https://t.co/AcXy5ZSX3n

@mehulkar Hi Mehul π
There are many opportunities to improve the UX on this site:
To improve the LCP take a look to this thread ππΌ https://t.co/z9vMjte4MD
The HTML is bigger 2.4 MB, am the TTFB and download time are huge π

#PerfTip for hero images, usually the element that impacts the LCP metric.
1οΈβ£ Use next-gen image format (WebP, AVIF, JPEG XL)
2οΈβ£ Preload the image
3οΈβ£ Don't use loading="lazy" attribute
4οΈβ£ Don't use decoding="async" attribute

@Arijitm_dev Hi π
Is not a good strategy to preload and prefech all the render-blocking resources.

@CherryJimbo Hi James π
Is a fast site, congrats ππΌ. I love to see AVIF images π€©
You can improve the LCP metric doing a preload the main image, and consider using responsive images to adapt them to the devices.

β‘οΈ To improve your Web Performance, you can preload different resource types.
Usually, you are preload the images, CSS, scripts, or fonts, but do you know that you can preload workers, fetch, or iframes?

Really good blog on Dropbox upload performance and Windows Client. https://t.co/kR9GqX3PFL #PerfTips
I just published Modern storage is plenty fast. It is the APIs that are bad. https://t.co/AC5WE2LpiZ
This is my take on modern storage APIs, what we are doing with Glommio to build on top of io_uring and fill a much needed gap of high performance storage systems in Rust.
So you want to use FiO for Windows? First question is Why? Second is use DiskSpd check the use power of IO Completion Ports on Diskspd and FiO not there. #PerfTips Thanks @vagnerpilar
By turning off `htmlTemplateEngine` and `dataTemplateEngine` in @eleven_ty config, I was able to shorten my sites build time from 0.24s to 0.17s.
Perf win!
