![]() ![]() ![]() With CTP2, we’ve addressed that – at this point, on average we should be at par or beating JIT64 on code quality. While with CTP1, we were in the same ball park as JIT64, we were still 10-20% slower on code quality, with some outliers. With CTP1, the focus was on throughput and to get some early feedback, and not so much on code quality (how fast the generated code executes). We’ve been careful to maintain our throughput wins, and this CTP should yield similar throughput numbers. When it comes to performance, CTP1 demonstrated that RyuJIT handily beats JIT64 on throughput (how fast the compiler generates code) by a factor of 2X. From the enthusiastic response we got from the first CTP, we’ll surely hear back with a few more bugs from our early adopters, i.e. We continue to look at ways to improve the overall quality of RyuJIT, and will likely discover a few more bugs along the way. Thanks to everyone who tried out the first CTP of RyuJIT and filed bug reports – we’ve fixed every single one of them, and at this point, RyuJIT doesn’t have any known bugs. NET), or complex ASP.NET workloads, or even simple Windows Store apps. NET Code Generation team) also added a number of performance tweaks and optimizations so that code generated using RyuJIT is generated fast (the throughput metric) and runs fast (the code quality metric).īut why stop there? We have thrown every test at our disposal at RyuJIT and it has come out with flying colors – whether it be running common server software using IKVM.NET (a Java Virtual Machine implemented in. Additionally, a host of other features have been added to achieve functional parity with JIT64. With CTP2, both of these features are supported. The two main features which weren’t supported in CTP1 were “opportunistic” tail calls and Edit & Continue. Improvements: Features, Reliability, Performance RyuJIT generates code that’s on average better than the existing JIT64, while it continues to maintain the 2X throughput wins over JIT64. This release of RyuJIT has equivalent functionality of existing JIT64: there aren’t any feature differences between RyuJIT and the existing JIT64 at this point. Two questions commonly asked were when would there be an update and when would it support feature X or Y that is in the existing 64-bit. The developer preview of RyuJIT, CTP1, received a thunderous response (so much so we had to post a FAQ soon after). It was written by Mani Ramaswamy, Program Manager for the. NET team’s new 64-bit Just-In-Time (JIT) compiler. This post announces an updated preview of the. ![]()
