OP的大盘机据说稳定性一般,但是对于刷PT或者其他什么用途,可能有一些特别的优势,最佳我就入手了一款OP 15EUR,的折扣机,虽然付款周期长有优惠,但是我只是试试,就不买长了,这个机配置如下:
- CPU: Intel Xeon L3426 - 1.86 GHz - 4 core(s)
- RAM: 16GB - DDR3
- Disk: 2x 2TB (HDD SATA)
- Network: Unmetered @ 1Gbps
- IP Address: 1 x IPV4 + 1 x IPv6 / 64
- Location: 法国 巴黎
- Price: 18.55USD/m
具体性能如何,还要实际测试一下,第一块硬盘的成绩如下:

另外OP的杜甫是跑不满G口的,这应该是因为上传口共享问题.
为了优化IO,所以要适当配置自动PT工具,我的配置是这样的.(实际情况根据磁盘能力配置,保持磁盘%util在75%以下最好,否则堵塞IO最后什么好处都没有!)

}
}实际效果如下图(理论单纯读写才60MB/s,所以这里一旦读写合并超过这个速度,将会产生很严重的问题!):
有人可能会觉得不能跑满上下行G口很可惜,这就见仁见智了,反正这个磁盘你要是敢跑满下行,那上行肯定是没速度的,最佳的刷种区间就是磁盘不太忙的时候.
