OSDL has created a mailing list for discussion of various topics
relating to "fastboot": reducing enterprise system start & restart time.

Topics of discussion are expected to include:

        - kexec
        - Two Kernel Monty
        - bootimg
        - and other similar technology

Other areas for discussion may include:

        - avoiding reprobe of devices,
        - fast system initialization after the kernel boots,
        - system-wide checkpoint/restart.

To subscribe, please visit:

Regards,
Andy

Systemwide checkpoint/restart... seems like suspend-to-disk to me...:

suspend-to-disk, but on the end, do not powerdown, but copy
swap/filesytems to spare disks, simulate suspend failure and
continue. On restart, copy back anddo restart. Perhaps with some LVM
magic this can be made acceptable?

1. [OSDL] Database Performance Numbers Posted on OSDL

OSDL has created a database workload that simulates an e-commerce book
store.  The back end of the database is SAP.  We have posted performance
statistics on the following web site:

      http://www.osdl.org/projects/dbt1prfrns/results

The table will eventually grow as more kernels are tested on different
systems.  Currently we have performance characteristics for a 2-way
system, 1 GB memory, utilizing 10 disk spindles for its database.  The
other performance measurements are conducted on a 8-way system, 16 GB
memory, utilizing 12 disk spindles for its database.  These runs involve
the same number of users accessing the database.

In addition to capturing database transaction numbers, data is captured
for I/O, memory usage, and CPU utilization.  Currently, the performance
work is being  conducted on 2.4 kernels.

However, STP is running a smaller version of this test on 2.5 kernels.
The first results from this run is located at

    http://khack.osdlab.org/stp/3441/

Is there any other kinds of information that would be useful to capture
and post?
