Ehcache3 持久性对性能的影响，无论如何都要使用磁盘层

如何解决Ehcache3 持久性对性能的影响，无论如何都要使用磁盘层

版本：Ehcache 3.8

// g++ main.cpp `pkg-config glfw3 glew --cflags --libs`
#include <GL/glew.h>
#include <GLFW/glfw3.h>
#include <iostream>

#define numVAOs 1
gluint renderingProgram;
gluint vao[numVAOs];

void CheckStatus( gluint obj,bool isShader )
{
    GLint status = GL_FALSE,log[ 1 << 11 ] = { 0 };
    ( isShader ? glGetShaderiv : glGetProgramiv )( obj,isShader ? GL_COMPILE_STATUS : GL_LINK_STATUS,&status );
    if( status == GL_TRUE ) return;
    ( isShader ? glGetShaderInfoLog : glGetProgramInfoLog )( obj,sizeof( log ),NULL,(GLchar*)log );
    std::cerr << (GLchar*)log << "\n";
    std::exit( EXIT_FAILURE );
}

void AttachShader( gluint program,GLenum type,const char* src )
{
    gluint shader = glCreateShader( type );
    glShaderSource( shader,1,&src,NULL );
    glCompileShader( shader );
    CheckStatus( shader,true );
    glAttachShader( program,shader );
    glDeleteShader( shader );
}

const char* const vert = R"GLSL(
#version 150
void main(void)
{
    gl_Position = vec4(0.0,0.0,1.0);
}
)GLSL";

const char* const frag = R"GLSL(
#version 150
out vec4 color;
void main(void)
{
    color = vec4(0.0,1.0,1.0);
}    
)GLSL";

int main(void)
{
    if (!glfwInit())
    {
        return -1;
    }

    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR,3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MInor,2);

    GLFWwindow* window = glfwCreateWindow(600,600,"Chapter2-program1",NULL);

    //Window or OpenGL context creation Failed
    if (!window)
    {
        glfwTerminate();        
        return -1;
    }

    glfwMakeContextCurrent(window);

    if (glewInit() != GLEW_OK)                 
    {
        std::cout << "Error!" << std::endl;
        exit(EXIT_FAILURE);
    }

    glfwSwapInterval(1);

    gluint renderingProgram = glCreateProgram();
    AttachShader( renderingProgram,GL_VERTEX_SHADER,vert );
    AttachShader( renderingProgram,GL_FRAGMENT_SHADER,frag );
    glLinkProgram( renderingProgram );
    CheckStatus( renderingProgram,false );
    
    glGenVertexArrays(numVAOs,vao);
    glBindVertexArray(vao[0]);

    /* Rendering loop- until the user closes the window */
    while (!glfwWindowShouldClose(window))
    {
        /* Render here */
        glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );
        
        gluseProgram(renderingProgram);
        glDrawArrays(GL_POINTS,1);

        /* Swap front and back buffers */
        glfwSwapBuffers(window);

        /* Poll for and process events */
        glfwPollEvents();
    }

    glfwDestroyWindow(window);
    glfwTerminate();   
    exit(EXIT_SUCCESS);
    return 0;
}

如果将persistent保持为true，是否对性能有任何影响。将使用磁盘层。我想知道持久标志只是为了可重启性还是对性能也有影响。
