Rerun these tests yourself on your own hardware using data that is a close match to your production data before drawing conclusions. <p> Notice that the individual file access times on Windows are dramatically slower than on the unix systems. This might be because the 100K BLOBs are all stored in a single directory and Windows is inefficient at searching directories with large numbers of files. The Windows file access times might be improved if the BLOBs were stored in a hierarchy of directories, rather than dumping them all into a single big directory. <h2>Key Points</h2> <ol> |
