Resolve application service spent 1 second

Question

We use abp in a really product for user. And there is api, it's so easy, but the response time for it is about 1 second. We think it shouldn't be, then we investigate it, found the execution time for the application service method is about 100 ms, and resolve the application service spent about 1 second.

We use IocManager.RegisterAssemblyByConvention(thisAssembly) for register.

Following screenshot is from the log file for investigation:

My questions are:

1. why the resolver spent so much time?
2. What's the correct way to fix this issue.

Answer 1

Before, we use default DependencyLifeStyle as Transient, and we make some changes to set DependencyLifeStyle to per request. And the resolve is so fast now.

The code changes as below:

public override void PreInitialize()
{
    IocManager.IocContainer.Kernel.ComponentRegistered += Kernel_ComponentRegistered;
}
private void Kernel_ComponentRegistered(string key, IHandler handler)
{
    foreach (var interceptor in interceptors)
    {
        if (interceptor.Key.IsAssignableFrom(handler.ComponentModel.Implementation))
        {
            handler.ComponentModel.Interceptors.Add(new InterceptorReference(interceptor.Value));
        }
    }   
    if (handler.ComponentModel.Implementation.Assembly.FullName.Contains(".Domain"))
    {
        if (handler.ComponentModel.LifestyleType == LifestyleType.Transient)
        {
            IocManager.IocContainer.Register(
            Component
                .For(handler.ComponentModel.Implementation)
                .ImplementedBy(handler.ComponentModel.Implementation)
                .LifestyleCustom<MsScopedLifestyleManager>()
                .IsDefault()
                .Named($"{key}-1")
                );
        }
    }
}
