Andrew,
Here are some benchmarks for the latest adaptive readahead patchset.
Most benchmarks have 3+ runs and have the numbers averaged.
However some testing times are short and not quite stable.
Most of them are carried out on my PC:
Seagate ST3250820A 250G/8M IDE disk, 512M Memory, AMD Sempron 2200+
Basic conclusions:
- equivalent performance in normal cases
- much better in: busy NFS server; sparse/backward reading
- adapts to memory size very well on randomly loading a file
These results look really good, and the code seems to be at least as
well-structured as the previous code. I think this argues for
inclusion.
