Gmail still slow. Unrelated: Why haven't Google implemented a Google.com-quality-level search for email?
Gmail's email search is already the best in the space, by far. I'm sure there are improvements to be made, but zero external pressure to make them.

Wrong. Counterexample: https://mail-archives.apache.org/mod_mbox/subversion-users/2... (Obtained by a quick search of "garbage collector double-free bug" - there are many others out there)
> Have you ever looked into ParaSail, Rust, ATS?
ParaSail and Rust don't have a GC, period, AFAIK. ATS is too strict for my liking. (I want a programming language that will refuse to compile if it can find a "counterexample" that will assert, but will compile something (with a warning and inserted runtime checks unless explicitly marked otherwise) even if it cannot prove something is correct.)

So basically one needs to re-implement smart pointers in Javascript, right ? What are the alternative to js style GC,for a language that wouldnt want to the developper to use manual memory allocation.I've heard about ARC.Are there other known architectures?
Object pools at the language level would be an alternative. (I.e. every object is allocated in a "pool", including pools. When a pool falls out of scope the entire pool is "freed". You can copy objects between pools as necessary.)
Does anyone else feel like Gmail has actually been getting slower in the past year? It feels like it takes a lot longer to load... And once it finally does load, you still end up having to wait a reasonable amount of time for Hangouts.

I don't touch Perl since 2004. Back then it used reference counting, not a GC.
Second, the post reads like a problem in the C code.

I was replying about GC alternatives for automatic memory management.

The question I have is why the Google Voice iPhone app does not have a search function AT ALL.

Exactly. All GC does is push down the code that can cause problems like double-frees into the language implementation. It doesn't magically make problems like double-free bugs impossible, like so many people say.

Then why did you respond to and quote something that was talking about something entirely different?

Yes, they'll eliminate the need for collection, by moving the overhead from a single collection to ever construction/destruction.
This may be worth it to get a constant framerate, but the overhead doesn't disappear. If anything, it could be greater: allocating from the heap usually costs more than an object allocation done by any sane VM.
