Subject:Weekly Falcon/InnoDB DBT2 Overview 2009-04-20
View as plain text  
Hello benchmark fans,

this week walldorf succeeded running a full set of our weekly
DBT2 overview with 10, 20, and 100 warehouses.

News for this week:
- No Falcon related crash on walldorf.
- caneland is still out of order and needs a hardware replacement.
* lu0009 and nehalem-1 were rebooted during the weekend and
therefore we have no results of them.

Todo:
  - Remove results from crashed runs in mean value calculation.
  - Add more information from INFORMATION_SCHEMA tables like Falcon's
  system memory 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.
  - Get a Solaris SPARC and Intel/AMD machine for DBT2.
