> if/when we up the size I can just see someone raising an issue about how using fio with 16GByte blocks at an iodepth of 8 didn't work...
Agreed. But we already see folks today using bs=1MB, numjobs=512, and iodepth=1024 as a "test." Folks just need to be aware of what IO they are really trying to do.
> Post the patch and we can take a look at it.
Here's my partial patch. I didn't (yet) change anything in blktrace.c, and the hack to parse.c is rough. Also I have a few make warnings to resolve.
Regards,
Jeff
