Zlib compresses better than LZO but it is slower. Say 'Y' if unsure.

+ help
+ Originally UBIFS did not support atime, because it looked like a bad idea due
+ increased flash wear. This option adds atime support and it is disabled by default
+ to preserve the old behavior. If you enable this option, UBIFS starts updating atime,
+ which means that file-system read operations will cause writes (inode atime
+ updates). This may affect file-system performance and increase flash device wear,
+ so be careful. How often atime is updated depends on the selected strategy:
+ strictatime is the "heavy", relatime is "lighter", etc.
+
+ If unsure, say 'N'
