h20牛人大佬:
刚才@wjbdada 派发了一堆linode小鸡,成功获取一个,射射老板。
第一次使用linode的机器,机器速度还不错,IO随便上G,得益于没有MJJ搞事吧。
- root@localhost:~# dd if=/dev/zero of=/dev/sdb bs=1M count=256 skip=200 oflag=sync
- 256+0 records in
- 256+0 records out
- 268435456 bytes (268 MB, 256 MiB) copied, 0.256125 s, 1.0 GB/s
- root@localhost:~# dd if=/dev/zero of=/test bs=1M count=1K
- 1024+0 records in
- 1024+0 records out
- 1073741824 bytes (1.1 GB, 1.0 GiB) copied, 1.0311 s, 1.0 GB/s
不过比较奇怪的是,这鸡的swap竟然用另外一个盘来做,可能存储上有特殊优化吧。
- NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
- sda 8:0 0 24.5G 0 disk /
- sdb 8:16 0 512M 0 disk
G口网速也很猛,随便下载点东西。
- % Total % Received % Xferd Average Speed Time Time Time Current
- Dload Upload Total Spent Left Speed
- 100 355M 100 355M 0 0 80.2M 0 0:00:04 0:00:04 –:–:– 80.2M
至于跨洋路由的话就一般般了。

- 5 * * * 请求超时。

- 跟踪完成。
看来可以搞点高负载的事情
