In the process of transferring FreeBSD onto my second PC at home I managed to get the /usr filesystem to swap from time optimization to space optimization. The /usr filesystem now reports 5.6 % fragmentation. Is this significant? How does one go about (to use the DOS terminology) compressing this filesystem? The above fragmentation figure is from fsck. Having had the filesystem swap over to space optimization, would it have swapped back to time optimization when I removed the large tar files after untarring them? If not, is the change capable of being reversed, and if so how? What are the performance penalties associated with space optimization percentage-wise? The /usr filesystem is about 196 meg with about 125 megs used after transferring from my first PC. Any help greatly appreciated. TIA. Brian
