Re: [PATCH v3 24/34] t/perf/p7519: speed up test using "test-tool touch"

> From: Jeff Hostetler <jeffhost@microsoft.com>
> 
> Change p7519 to use a single "test-tool touch" command to update
> the mtime on a series of (thousands) files instead of invoking
> thousands of commands to update a single file.
> 
> This is primarily for Windows where process creation is so
> very slow and reduces the test run time by minutes.
