I'm wondering in freeBSD, if I have a directory with 10,000 files, or maybe even 100,000 files, each about 5 kb long. Wondering will reading and writing to any one of these files in C be affected by the sheer number of these files? Will the access time be affected significantly?
Just wondering because not sure whether I should put these data in a database or just use files with unique names.
Also will separating the files into many directories help?
Looking up .../x/12/34/56 can be done in logarithmic time (i.e., look up
.../x/12, then .../x/12/34, then .../x/12/34/56); looking up .../y/123456 (unless some optimization has been added) will require a linear scan
through the directory. In short, don't go there...
