| |
To whom it may concern,
Hello, this is Chulho Kang at Seoul National University, the Republic of Korea. I have a question regarding dm-delay component.
I know this implementation has a limited delay granularity (1ms) I hope to emulate devices with sub-millisecond delays through the high-resolution Linux timers.
Could I ask you for advice? I want to try out this component to “storage performance analysis” that I’m researching My aim is to emulate SSD devices latency of being reduced from mili-sec to nano-sec on ramdisk using dm-delay.
Best regards, - Chulho Kang
