Hi Charu, The ram disks under Linux have several limitations that probably make them unsuitable for what you are trying to do. I believe that they were designed primarily for OS installs from floppy disk. The Linux filesystems do not do synchronous metadata writes and are therefor very fast. I do not think you need to do anything special to get tmpfs like performance from ext2. If you are going to put a large number of files into a directory, then there is an experimental filesystem called reiserfs you might want to try. You can get more information from:

I hope this helps,
Jim
