Have you profiled your code to see what calls exactly are taking the most
time? I have a feeling it's these:
isFilePackageAtPath
kLSItemInfoIsInvisible
kFSNodeLockedMask
kFSCatInfoCreateDate
kFSCatInfoContentMod
kFSCatInfoBackupDate
kFSCatInfoAccessDate
And parsing "ls" output won't get you these (besides, parsing "ls" is a
dirty hack anyway). You probably want to try dropping down to
CFURLEnumerator and asking it to prefetch the desired attributes. Or, if
you're targeting pre-10.6 then FSGetCatalogInfoBulk().
