Greetings,
Back in 2004 O_DIRECT support was requested, and the response was that it was already on the todo list:
I have run into cache pollution issues causing degraded performance when using tar to copy/un-tar files to an active server, as seems to not be terribly uncommon:
I am wondering what happened to this request, as modern tar still does not seem to support a direct mode, or other options to prevent cache pollution when un-taring large archives.
Has anybody else found creative solutions for this situation?
Thanks,
Aaron
