环境 openEuler 22.03 (LTS-SP1)  通过dsoftbus-1.0.0-3-oe2203sp1.aarch64.rpm包安装 软总线服务端，客户端参考示例代码调用 hichain认证，部分代码如下。发现调用InitDeviceAuthService接口后, 单核cpu占用率从 30% 升高到70%左右，调用DestroyDeviceAuthService接口后，cpu也不会降低，请问怎样优化，让cpu占用率降低

int HichainInit()

{

    uint32_t num;

    int ret;

    ret = GetDevUdid(g_udid, MAX_UDID_LEN);

    if (ret) {

        ZLOG_ERROR("GetDevUdid fail:%d\n", ret);

        return ret;

    }

    ret = InitDeviceAuthService();

    if (ret != 0) {

        ZLOG_ERROR("InitDeviceAuthService fail:%d\n", ret);

        return ret;

    }

    g_hichainGmInstance = GetGmInstance();

    if (g_hichainGmInstance == NULL) {

        ZLOG_ERROR("GetGmInstance fail\n");

        ret = -1;

        goto err_GetGmInstance;

    }

    ret = HichainGmRegCallback();

    if (ret != 0) {

        ZLOG_ERROR("HichainGmregCallback fail.:%d\n", ret);

        goto err_HichainGmRegCallback;

    }

    ret = HichainGmGetGroupInfo(&groupVec, &num);

    if (ret != 0) {

        printf("HichainGmGetGroupInfo fail:%d\n", ret);

        //goto err_HichainGmGetGroupInfo;

        return ret;

    }

    if (num == 0) {

        ret = HichainGmCreatGroup();

        if (ret) {

            printf("HichainGmCreatGroup fail:%d\n", ret);

            goto err_HichainGmCreatGroup;

        }

    } else {

        printf("HichainGmGetGroupInfo:num=%u\n", num);

        HichainSaveGroupID(groupVec);

        HichainGmDestroyGroupInfo(&groupVec);

    }

    return 0;

 

err_HichainGmCreatGroup:

err_HichainGmGetGroupInfo:

    HichainGmUnRegCallback();

err_HichainGmRegCallback:

err_GetGmInstance:

    DestroyDeviceAuthService();

    return ret;
