I love TypeScript for it's features, but version 0.9 is barely usable. I've been using VS for years and I've never encountered severe performance issues. TS 0.9 makes devenv.exe use a lot of RAM and CPU. Code editor often hangs for up to 10s. It takes a lot of time to compile a TS file. I hope you will release a patch soon. Please let us know as soon as you know when the patch will be released.

Better intellisense due to generics is great, but I'm completely unable to use intellisense because of extremely slow inference. Hope to see this resolved soon.

I like and use TypeScript. However, like many other people I am not using the 0.9 release because of performance issues. All my code is staying on 0.8.x for now until the issues have been redressed.

Even after disabling the Web Essentials plugin and patching the bug with it removing characters from your paths, the compiler is quite slow. Our project of ~300 files takes ~30 seconds to compile using command line.
Is there any timeline for 0.9.1 release?

I like the new features, but they're currently not worth it if they slow the compiler to a halt.
The project I'm currently working on has 325 TypeScript files, and that might double by the time the project is feature complete. Compilation time has quadrupled in this release.

While I'm seeing the performance problem just like everyone else, it has thus far been acceptable. The language additions (e.g. generics) are well worth the sacrifice in compile time.
I did have to compile all my files in a single command rather than one-by-one to get compile under 20 seconds. Looking forward to the promised compiler speed improvements.

From my perspective, all the problems that other users have originate from using WebEssentials plugin for VS2012, which seem to be somehow incompatibile with this version of compiler(Try disable buidling all files on project build). Compiling the project with command line tool (using Node.js) takes seconds. Hope it helps someone.

Love the new features, but I am also experiencing frustratingly slow compiler performance with 0.9.0.1 and VS 2012.

Love the new language features. Wish I could actually use them. Compiler performance brings everything to a halt. VS memory usage climbs by the gigabytes. Our project has ~35 .ts files. Building our solution with 0.9.01 takes forever. Sadly, we're stuck with the previous version until compiler performance (and memory usage) improves.

Given a fairly complex project I find that I have to stop and start VS2012 because the TypeScript tooling has got confused and doesn't pick up changes. It suggests to me that the dependency tree amongst .ts and .d.ts components in a project is not good enough or the caching is suspect. In addition I find I have to remove the lines in the debug files: "//@ sourceMappingURL=...". But hey!

release 0.9.1 unusable due to compiler speed. 0.8 was great as well as the language is.

UPDATED: downgrading from 4 stars to 2 after a week. This is unusably slow. I feel I'm working over a 9600 baud modem.
A good release (I think) but my certainty would be improved if you actually linked your releases to issues. You have a 0.9.0.1 release to match this, but no issues (in any state) are associated with it. Please consider updating your issue tracker, or else what's the point?

This version 0.9.0 is a big step backwards compared to the 0.8 release. Compiler performance is nearly unusable. Debugging doesn't work as expected anymore and VS2012 freezes very often. Typescript is great but this release isn't ready to be used for production. Stick with version 0.8 untill the major issues of this version are resolved.

The latest release is completely unusable. I'm seeing compile times upwards of ten seconds per file.

Looks good; however I was expecting to be able to add string-based enum constants to keep my parameters strongly typed. I read somewhere this version would have it, but the VS install does not.

string constant overloading + generics + improved intellisense
all the best we needed
