Moreover, it supports multi-threading out of the box! Topaz performs better than Jint in performance. Topaz Performance on server-side rendering hits 3700 per second. I hear you are saying tell me the numbers. He has written an excellent Esprima port which makes writing JS runtime a piece of cake. The only downside of Jint is it does not support parallel execution on even simple function calls. Jint is excellent with its extreme support for Javascript native data structures. Jint is very successful in terms of performance (I get ~1600 page views per second) and memory consumption is also good. Moreover, memory consumption was too high: 800 MB for a couple of page rendering. I barely served 100 requests per second on my desktop. Clearscript uses Google's v8 C++ engine using locks and marshaling everywhere which slows down things. After a while, I have realized Razor was not flexible for my microservice architecture and business needs. I have developed a server-side HTML page rendering application using Razor. Topaz functions can be safely called from multiple threads in parallel. Jint functions are not thread-safe even when they do not manipulate any shared object. Topaz is significantly faster than Jint on this benchmark. Benchmark 2 (1M manipulations on arbitrary. Moreover, Topaz can iterate loops in parallel using. Topaz is significantly faster than Jint in simple for loops. However, it is extremely slow (1M Loop in 8 seconds!) if the script code interacts with host. | Jint Simple For | 627.941 ms | 11.4362 ms | 10.1379 ms |ĬlearScript V8 Engine is super optimized for isolated scripts that don't communicate with the host. Result: | Method | Mean | Error | StdDev | Intel Core i7-6850K CPU 3.60GHz (Skylake), 1 CPU, 12 logical and 6 physical cores Environment: BenchmarkDotNet=v0.13.1, OS=Windows 0 ![]() However, there might be different scenarios in which some slower engines can perform better. Overall Topaz's performance is better than Clearscript and Jint's. In the future, we might add class support. The latest Javascript Language features are mostly implemented.įor now, there is no class support, because it is not intended to write big applications using Topaz. Topaz will support everything that will make benefits.įor example, Javascript Array is very useful for data operations and it is fully implemented and available. if you write const a = 3.0 the a variable's type will be double and so on. NET runtime, therefore every variable written in the script is a. Topaz will not be a JS engine that supports entire Javascript runtime features, but it will be a lightweight script interpreter which provides the full power of. In server-side applications using such an engine does not perform well. ![]() However, that process requires marshaling and locking and also requires a lot of resources. There are v8 wrappers like ClearScript to make use of v8 functionality in the. The Javascript engines like v8 convert Javascript into machine code. It parses abstract syntax tree and executes instructions in the. ![]() Topaz does not convert Javascript code into machine code directly. It must be blazingly fast in both execution and load. The scripting engine should be lock free. With Topaz, you can turn off 'undefined', control asignment scope of variables and disable null reference exceptions without breaking the flow and much more. Syntax level options which simplify script language is necessary to ease scripting support of many products. Topaz does not restrict multi-thread usage. That is acceptable for desktop environments but not pleasing for server-side execution. Existing Javascript Engines run scripts in single-thread.
