为非线程安全代码构建工作线程池

在 .net 框架中包装非线程安全代码的最佳方法是什么？

我有一个第三方库，由于使用静态变量，该库不是线程安全的。重写它不是一个选择。该库由接收大量并发调用的 ASP.NET Web 服务使用。

我目前已将其包装在一个代理类中，该代理类使用锁来确保线程安全：

private static readonly object oneThreadAtATimePlease = new object();
public ISomething CalculateSomething(int someValue)
{
    lock (oneThreadAtATimePlease)
    {
        return new UnsafeLibrary(someValue).DoSomething();
    }
}

性能很差，因为多个调用者必须等待锁，但结果是正确的。

我想通过运行该库的多个实例（每个实例都在其自己的 AppDomain 中）来提高性能。这是一个合理的做法吗？有什么好的示例代码可以推荐吗？

What's the best way to wrap non-thread-safe code in the .net framework?

I've got a third-party library that isn't thread safe due to its use of static variables. Rewriting it isn't an option. This library is used by an asp.net web service that receives lots of simultaneous calls.

I've currently got it wrapped in a proxy class that uses locks to ensure thread safety:

private static readonly object oneThreadAtATimePlease = new object();
public ISomething CalculateSomething(int someValue)
{
    lock (oneThreadAtATimePlease)
    {
        return new UnsafeLibrary(someValue).DoSomething();
    }
}

Performance is poor since multiple callers have to wait for the lock, but the results are correct.

I'd like to improve performance by running multiple instances of this library, each in its own AppDomain. Is this a reasonable approach? Any good sample code to recommend?
