Hey everyone, At [Emergence Engineering](https://emergence-engineering.com/) we were curious about Lexical, Meta’s relatively new rich text editor framework. We’ve been working with ProseMirror for a long time, and a new contender in this space is always interesting, especially if it’s backed by a huge company. So we tested both on the performance front to see if Meta’s solution is better or not: > **[Rich Text Editors in Action: Stress Test On Lexical and ProseMirror](https://emergence-engineering.com/blog/lexical-prosemirror-comparison)** > > This article explores how Lexical and ProseMirror handle long-term use and heavy data stress. My conclusion: ProseMirror wins. ---

Thanks, interesting post! > Meanwhile, we recorded the timestamps in every 200 nodes to see how the increasing content affects their speed (and loss). This statement wasn’t completely clear to me. > **Conclusions** : Lexical’s total of script executing time increases faster than ProseMirror’s, which is probably linked to its **faster** handling of increasing content and more frequent garbage collection. I think this should be “slower handling of increasing content”. ![image](https://discuss.prosemirror.net/uploads/secondsite/original/2X/6/6da2f90c0399860bf9c1cb9f8dbf411ad6f99aa7.png) Memory usage difference is over 2 orders of magnitude?! ---

Hey, we just got an update for this article and the memory consumption was caused by Lexical’s history plugin. Without that they’re kind of similar, will post an update soon! ---

It seems like the only place Lexical surpasses ProseMirror is in `LayoutCount`. I wonder if, in the long run, ProseMirror could be optimized in this regard. ---

For me it looks like Lexical has a little bit better performance, worse docs, same bundle size, worse community / tooling. ---

I don’t understand how Lexical has better performance. The results seem to suggest otherwise except for that single point. Can you elaborate on your thoughts? ---

It’s in the first graph: it does more nodes in less time. I find it hard to make real sense of the results too btw 🙂 The higher scriptTime could mean that it would choke the even queue earlier ( with more plugins etc ), then ProseMirror could be faster, but I didn’t want to get into such theories. Will publish the updated results this week ( without History, which caused the high memory usage ), they show a little bit of lead for Lexical in every graph except memory which is still a bit higher. ---

Does Lexical include history in its core? I feel like testing without history paints an unrealistic picture of real-world use, although it does get to the core functionality better. I see I read the NodeCount results inverse of what was intended though, so that explains a bit of my confusion. I still agree that ProseMirror is the right choice these days. I did a lot of research into Lexical and started implementing it before I threw up my hands and moved to ProseMirror (via TipTap.) ---

Update: we’ve re-tested with disabled History in Lexical, now they’re close with Lexical usually leading a little bit. Check the updated article! Still, ProseMirror is the better choice nowadays.
