Hi, Andrew,
Here are more test results for v6 of the memory controller posted at
http://lkml.org/lkml/2007/8/17/69
The tests were run under three different configurations
1. disabled - the memory controller was not compiled in
2. notmnted - the memory controller was compiled in, but the container
filesystem was not mounted (one could view this configuration as
a memory controller with no limits enforced)
3. limit400 - the memory controller was compiled in and the container
running the tests was limited to 400 MB of memory usage.
Tests run
----------
1. lmbench
2. ltp
3. vmmstress
4. aim9
5. memtest (succeeded)
