在R中快速机器上的运行时间非常慢

Question

我对新机器的R分析运行有点慢。所以我进行了一些基准测试以查看最新情况并发现我排在最后：

> res = benchmark_std()

我的电脑规格让我怀疑这些结果：

> get_cpu()
$`vendor_id`
[1] "GenuineIntel"

$model_name
[1] "Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz"

$no_of_cores
[1] 12

> get_ram()
17.2 GB

> get_sys_details()
$`sys_info`$`sysname`
[1] "Windows"

$`sys_info`$release
[1] ">= 8 x64"

$`sys_info`$machine
[1] "x86-64"

$r_version$version.string
[1] "R version 3.5.0 (2018-04-23)"

我对恶意软件持怀疑态度，因为这是一台新机器。有谁知道这个问题是什么？
