Pretty sure v8 gets a few orders of magnitude more attention and development resources than jvm and graal.

Pretty sure you don't know how many JVM implementations are out there since around 2000.

By the way does V8 already handle TB sized heaps with 1ms pause?

Or is able to scale down into embedded devices with hundred KB, while respecting real time constraints?

Or able to have an implementation in JS itself?

Or does V8 cache JIT code across sessions and improves it via additional PGO data gathered across the sessions history?

I am not speaking of the same implementation here, rather a taste of what is out there on the Java world.

Lower memory consumption too. This is good news, I am worried for the future of Mozilla and Firefox.

It's nice to see some actual good news involving Firefox. With all of the leadership and financial struggles lately, it's made me worry that the browser I've been using for the last 17 years doesn't have long to live. Hopefully that is not the case.

Agreed - what I don't get is: ( https://www.theregister.com/2020/08/14/mozilla_google_search... ) However, our source told us Moz will likely pocket $400m to $450m a year between now and 2023 from the arrangement, citing internal discussions held earlier this year. (... snip ...) According to the organization's latest financial figures [PDF], $430m of its 2018 total revenue of $451m came from those internet giants –…

Re format, I mostly see people use markdown syntax.

Here is the link that doesn't require a Google login: https://archive.is/SFFph

thank you! interestingly a very similar link appears to not require a google login, but requires javascript: https://groups.google.com/d/topic/mozilla.dev.platform/1PHhx... i wonder what's going on.

Weird! But thanks - we've changed to that from https://groups.google.com/g/mozilla.dev.platform/c/1PHhxBxSe....

10% faster with less memory use and simpler code / data models - nice work! Excited to see the end result.

Hopefully HN users on nightly are able to try it out and give feedback.

They well deserve some donations, and I just sent some quid, but would also buy some merchandise for me and gifts for friends/relatives if shipping costs make it worth, but apparently there's no way to purchase from them. A search brought some sites selling Mozilla branded items, but I'd like to be sure the money, or most of it, goes to the Mozilla Foundation. Any suggestions? Thanks.

Earlier quoted context omitted.

The last thing I want in my browser is a JVM.

The brower already has a VM, and from the same people and the same principles who made the Java JVM JIT and the fast Smalltalk one back in the 90s... Lars Bak, the v8 head: "In 1994, he joined LongView Technologies LLC, where he designed and implemented high performance virtual machines for both Smalltalk and Java. After Sun Microsystems acquired LongView in 1997, Bak became engineering manager and technical lead in…

I heard at one point that Hotspot had crossed a million lines of code. Looks like V8 is close to 2 million sLOC.

The same source says SpiderMonkey is about 540k sLOC.

Bak has learned a lot of lessons along the way I'm sure, and unless Cliff Click decides to write VMs again (sounds like he's semi-retired, doing something else) then he may be the best person for the job. But nobody's perfect. For me this is Exhibits A-C.

Is there any way to directly donate to firefox (and not other mozilla related things)?

Every single day hundreds of people are working on making Firefox better.

Would be great if Firefox set up monthly donations system on Patreon, OpenCollective or similar platform, and all donations would go directly to browser development.
