🔍 3 #Android apps coded with 3 different techs, all running a heavy calculation alongside.

Interesting results:
• In #Flutter & #Compose it blocks the animation.
• In #ReactNative, animations still play smoothly. 🤯

Why?
Here's a thread about threads and #performance 🧵 1/6

[Alexandre Moureaux @almouro]

Been a while since I posted here, but happy to announce

Who needs an excuse to come to the most beautiful city in the world? ♥️🇫🇷🥐

Only one week left to submit your talk to @ReactNativeConn ! 😱

[Alexandre Moureaux @almouro]

I've been using #ReactNative for almost 10 years 👴

All my apps had several libs signed by @zoontek in their package.json 🤩

You don't want to miss Mathieu sharing all his experience at @ReactNativeConn! 🔥

[React Native Connection @ReactNativeConn]

This year we’re proud to open the lineup announcements with one of the pillars of the French - or should we rather say International - React Native community.
Folks, please welcome @zoontek.me!

[Alexandre Moureaux @almouro]

@radko93 @ADoubovetzky @bam_lab Thanks for pinging! 🙏 Taking a look 👀

[Alexandre Moureaux @almouro]

It was my pleasure to dive with the audience into some intensive #ReactNative #performance debugging! 🤓

We've gone through:
⚛️ @ReactDevTools
🌐 Chrome JS profiler
🤖 Android Studio
🍎 Xcode instruments
🔦 Flashlight
⚛️ React compiler

All that in a single morning 🔥

[React Native London @RNLConf]

Big turnout for the performance workshop by @almouro this morning! ☀️☀️☀️

[React Native London @RNLConf]

It's happening next week! 🙌

We're so excited to have such a great cohort of React Native experts joining us for the very first RNLConf! ❤️

See you all soon 👋

[Alexandre Moureaux @almouro]

Hello @reactnative community in London 🇬🇧

My good friend @ludwig_vaan is looking for a place to stay for @RNLConf!

He will definitely return the favor if you want to visit beautiful Bordeaux 🍷🇫🇷

I can attest he will take you to all the good spots to visit/eat/drink there ❤️

[Ludwig Vantours @ludwig_vaan]

👋 Hey @RNLConf participants! I’ll be in London for the conference soon, and wow, hotels are no joke! 😅💸

Since I’m self-funding this trip as a fresh freelancer, I’m hoping to find a more budget-friendly stay.

Anyone open to a bit of Couchsurfing or have some good leads? Let me know in PM!

[Alexandre Moureaux @almouro]

@Dennis_De_Table Ah yes that seems likely!
Need to check on other phones 👀

[Alexandre Moureaux @almouro]

On #Android, the battery usage screen gives interesting #GreenIT insights 👀

My breakdown usually looks like:
🌐 Network: 50%
⚙️ CPU: 30%
📱 Screen: 10%

Android users, what's yours? 🙏
Curious to see how different everyone's results are 🤔

[Alexandre Moureaux @almouro]

@Dennis_De_Table Arf maybe that's a Pixel only thing 🥲

I'm on pixel 8 Android 14 and I get this nice dropdown to choose between apps and systems

[Alexandre Moureaux @almouro]

Is it me or did @v0 get a lot better? 😮

📈I asked it to generate a #performance & #accessibility audit report for an app,
I'm pretty satisfied with the result! 🥳

🍒 Cherry on top: it managed to add logic to change the video current time, based on the step being clicked

[React Native London @RNLConf]

We are incredibly excited to announce our next speakers who will take the stage at RNLConf 🎉

@dan_abramov2 and @mozzius will be telling "The Bluesky Story" in an exclusive 🔥 Fireside Interview 🔥 hosted by our good friend @tazsingh ♥️

We're super excited to have them 🙌

[Alexandre Moureaux @almouro]

Trop content d'être au @DevFestToulouse pour une belle session de live coding! 🥳
On va:

🔍 Explorer le code source d'Android
💡 Apprendre plus sur les perfs Android
📈 Mesurer FPS, CPU et RAM

En gros, on recode Flashlight (https://t.co/u1F9XRXKJe) en 100 lignes de #Kotlin🤞

[DevFest Toulouse @DevFestToulouse]

Live coding : créons un outil de mesure de perf pour Android 📱

Plongez avec nous dans l'art de mesurer la performance de n'importe quelle app grâce à adb. @almouro de BAM vous guidera.

[React Native London @RNLConf]

Is your React Native app not running as smoothly as you'd like? 🧈

Join @almouro at RNLConf for a hands-on workshop on debugging performance issues and optimizing your app.

🧰 Tools, techniques, and real-world fixes—don't miss it!

[Alexandre Moureaux @almouro]

@c_isambert @mo__javad @RNLConf Definitely! I'll use some @bam_lab people as performance guinea pigs 🐹🐹

[Alexandre Moureaux @almouro]

@iponikar @schlimmson In React Native, thanks to @HermesEngine, bundle size in itself doesn't affect performance 🥳

See for instance this fun experiment by @El_Niebo

https://t.co/D9GZbaJoed

[Alexandre Moureaux @almouro]

I've always wanted to check the impact of a large JS bundle on a #ReactNative app start time 📈

Without @HermesEngine, it was horrible (see gif) 😱
- 30MB JS on the left
- 1MB on the right

@El_Niebo experimented to verify that 🔍
