i do recall, on DOS systems, that there was a major slowdown of
scanning files which JAM brought to the forefront... the problem was
actually in the file system and the way that the OS managed FAT* areas
with large numbers of files... folks thought they were putting (eg) 400 message areas in one directory but they didn't realize they were really putting 1600 files in one directory... splitting the areas into
directories with less than 255 _files_ (63 JAM areas) per directory
sped the processing up by at least a magnitude...

Luckily those limitations no longer exist :-)
