Instead, I manually trigger the auto suggestions using Ctrl+Space when needed. I personally turn off autosuggestions so that they don’t slow down my typing. Unfortunately, anything else makes it really laggy and slow.

Make sure that you are using the 64 bits version of Eclipse and of the Oracle JDK. More often than not, every new JDK and Eclipse version includes fixes and optimizations from previous versions. If not, look no further for performance boosts… Tip 1 : Always run the latest JDK and Eclipse. Note: I assume that you already have an SSD and at least 8Gb of RAM. Classes will open faster, jumping from one definition to another will be faster. Viewing method javadocs will be faster… Unfortunately, none of that can be timed precisely so there is no specific benchmark about the actual speed gains for each tip. : most of those tips will speed up your Eclipse experience, not just the startup time.
I’ve described each tip for Windows, Linux and MacOS users. Once you have gone through all the optimization tips, Eclipse should start within 10 seconds and run much smoother than before.
I was asked by a few people to share my tips on how I was able to speed it up so here we go… As a side note, this article is not about comparing IDEs, please refrain from displaying your hate for the IDE or your preference for another… This post is just about optimizations that help Eclipse run faster for those who use it. About a month ago, I blogged about my love/hate relationship with Eclipse.
