Once you get below a couple seconds, you're unlikely to be measuring the speed of the SSG, you're measuring I/O latency. Suggesting it could be faster or slower is pointless unless you have identical hardware. The same disks, CPU, and RAM, the same OS, down to the kernel version. The same running processes.

Even a 5400 rpm hard disk delivers reads in the hundreds of megabytes per second.

75 pages should never take several seconds. Or even "under a couple of seconds". It should bot even register in the radar.

Hundreds of megabytes per second is decidedly on the high side for such a device to begin with, but it only holds for big sequential writes. For random I/O, which is what this is, you’re more likely to average 0.5–5MB/s plus latency.

I was assuming it would be more CPU- than I/O-bound, because hopefully we’re all using SSDs these days, and because Hexo’s website uses similar time figures in its preposterous “blazing fast” description.

shakna’s gone too far the other way (a couple of seconds for a load like this (~80 file reads, processing, ~80 writes, all of the files under 64KB) is easily enough that if it’s measuring I/O latency there’s either something wrong with your machine or you have a slow HDD and wrote your I/O code the wrong way), but my 200ms certainly already reaches the point where CPU, disk and OS/antivirus solution all matter significantly.
