Subject:Weekly Falcon/InnoDB DBT2 Overview 2008-11-17
View as plain text  
Hello benchmark fans,

you missed last weeks Weekly Falcon/InnoDB DBT2 Overview, because I was
on vacation.

News for this week:
- walldorf has problems running DBT2 currently. I have to analyze the
root cause.
- No dramatic performance changes; all changes are in the area of noise.
- nehalem-1 runs ok but until we have a reasonable RAID setup on it
we should not consider the numbers. I just got an approval for a
softraid RAID10 setup with 6 SATA disks and I am still waiting for the
hardware to be delivered and built in.

*** walldorf ***
****************
* Problems on walldorf. To be analyzed.

Todo:
  - Remove results from crashed runs in mean value calculation.
  - Add more information from INFORMATION_SCHEMA tables like Falcon's
  system memore usage or summary of active/pending_commit/pending_completion.
  Also talk to Ann to get more insight to Falcon metrics.
  - On walldorf put falcon_serial_log_dir to SATA disk to see
  whether the battery backed up RAID controller is the source of
  huge performance gain we saw lately.
  - Configure OProfile runs to run once per concurrency level.

Setup: datadir is on RAID10 and logdir is on separate disk (for InnoDB).

Configuration is:
