Subject: Q: Shared Memory vs. Ramdisk?
Date: Wed, 23 Feb 2005 05:41:30 -0500 (EST) [thread overview]
Message-ID: <Pine.LNX.4.61.0502230535220.4512@winds.org> (raw)
Hi all,
I have an application on x86-64 that will require me sharing two memory
segments upwards of 10+ GB each among several processes. Would it be better
performance-wise to mmap in two files from a tmpfs filesystem, or, create two
large ramdisks (/dev/ram0 & /dev/ram1) and mmap those in?
I'm not concerned about swap, but rather just trying to avoid as much kernel
overhead as possible while accessing gobs of memory.
Thanks,
-Byron
