-prefix-free lets you use only unprefixed CSS properties everywhere. It works behind the scenes, adding the current browser’s prefix to any CSS code, only when it’s needed.
“[-prefix-free is] fantastic, top-notch work! Thank you for creating and sharing it.”
— Eric Meyer

Properties as well in Firefox < 3.6.Check this page’s stylesheet ;-)
You can also visit the Test Drive page, type in any code you want and check out how it would get prefixed for the current browser.
Just include prefixfree.js anywhere in your page. It is recommended to put it right after the stylesheets, to minimize FOUC
That’s it, you’re done!
The target browser support is IE9+, Opera 10+, Firefox 3.5+, Safari 4+ and Chrome on desktop and Mobile Safari, Android browser, Chrome and Opera Mobile on mobile.
If it doesn’t work in any of those, it’s a bug so please report it. Just before you do, please make sure that it’s not because the browser doesn’t support a CSS3 feature at all, even with a prefix.
In older browsers like IE8, nothing will break, just properties won’t get prefixed. Which wouldn’t be useful anyway as IE8 doesn’t support much CSS3 ;)
Test the prefixing that -prefix-free would do for this browser, by writing some CSS below:
Caching can greatly improve performance by reducing the number of database queries. Consider using:
"High-Performance Java Persistence" by Vlad Mihalcea is a comprehensive guide for mastering data access in Java, bridging application code with database performance optimization techniques. The book provides actionable strategies for optimizing JDBC, JPA, Hibernate, and jOOQ, covering topics like connection pooling, batch updates, and efficient fetching strategies.

Batching and inserts/updates
Database queries can be a major bottleneck in Java persistence. To optimize queries:
Just because you have an @Entity class doesn't mean you should use it for read-only views. Mapping a full Entity with all its relationships just to display a username and email is wasteful. ✅ The Fix: Use Constructor Expressions (DTO projections). You skip the Dirty Checking mechanism and the Persistence Context overhead.
