I have no problem with this. I understand the concept of and benefits of a cache. But what I do not understand is why, as the cache grows (seemingly out of my control), the amount that waits to be flushed to the disk grows, making each successive flush take longer. Or at least this is what it looks like is happening. So, when the OS has obtained, say, 24 GB of cache, each time it needs to flush it takes longer as there is so much.
I don't think it is waiting to be flushed. It is cached so that the next _read_ will come from memory. Yes, you will not read, but the kernel doesn't know that.
