putting "/tmp" to memory
"to memory" means: mounting a ~2 GByte filesystem [ tmpfs?, or ramfs? ], and put the "/tmp" on it. [ e.g.: 4 GByte ram in the pc ]. what to write in the "/etc/fstab"? I would like to collect the [ answers too:P ]: Advantages: - Memory is way faster then HDD/SSD, so it could speed things up - "SSD amortization" is less Disadvantages: - Security?

ionice...
Hey, anyone has some successful experience with ionice? I tried it with 'idle' (-c 3) parameter. When I did a quick test (find /), it seemed to work with frequent pauses (I guess waiting for idle). But when I used it on my big tar, it made it worse than without... which seems counter-intuitive. Thx, JD

heavy IO load when working with sparse files (centos 6.4)
Dear List, We have noticed a variety of reproducible conditions working with sparse files on multiple servers under load with CentOS 6.4. The short story is that processes that read / write sparse files with large "holes" can generate an IO storm. Oddly, this only happens with holes and not with the sections of the files that contain data. We have seen extremely high IO load for
