The program is simple, there are 1000 - 3000 files with each being 1KB. The program repeated the following processes on each file: open(), read(), close(). The total time is measured with/without inline data support. The results are as follows (seconds), #files without with 1000 17.3674 8.7186 2000 35.4848 17.7646 3000 53.2164 26.4374 Cheers, Li Wang
