Not everything you read on the Internet is true.
That "10x-15x" figure is not particularly accurate, but there was a
particular corner-case configuration where reiserfs was significantly
faster than ext[23]. However, it requires reiserfs is used with tail
packing enabled, which is not what most users actually use because it
negatively affects performance for most loads.
In addition to that, changes have been made to ext3 that significantly
improved performance for some configurations, including the one that is
the source of the "10x-15x" approximation. reiserfs would still be
quicker, if tail packing was enabled, but ext3's performance would be
much closer now.
It's important to note that this configuration is not one that most
users would ever see, and the small files must be less than 1kB (not
4kB, as quoted) for that magnitude of difference.

I disagree.
