That would fix this particular case, but my thought were more along a general comparison of BLOB and file APIs. While ext2 open is dominated by directory lookup times when opening files, reiserfs and MySQL perform logarithmically here. On the other hand, during read and write phases ext2 and reiserfs as well as all other file systems have an API that allows them partial object reads and writes as well as seeking within that object. The question is, what does the MySQL BLOB API provide and how does it relate to performance of applications making use of the MySQL BLOB API?
