Joe: The index is modified very often and need to be flushed at regular interval, I don't want to handle read and write. JB: I already use mmap. JD: I already tried posix_fadvise with POSIX_FADV_WILLNEED, but this is not rock solid, if not used for a long time, data are not in the cache anymore. Bryn: mlock is what I was looking for. I'll make a try now. Thanks to the community.
