Improving Ext3 performance by placing the journal on a Flash Disk
Running a Linux Server on a HW RAID6 / LVM setup we are plagued by the fact that heavy activity on one file system will impact performance on all of them. If there is an active writer on one file system (especially meta data updates) then all other file systems will face extreme performance degradation. Especially read performance fell right through the floor. Response times become large and highly fluctuating.
The problem seems to even exist on simple single disk systems as is explained in this Ubuntu bug 131094.
...
So tonight, after I had connected that new disk to a spare SATA port I was ready to go.

Performance Impact
After running the setup for a few days, I draw the following conclusions:
*
The general slowness of all file access, caused by a single heavy write is reduced so much that it does not interfear with daily work anymore. *
The hardlink backup (using rsync to keep a copy of the files, with hardlinks to those that have not changed) is about twice as fast. *
The tape based backup (bacula, running at the same time as the hardlink backup) is about twice as fast as well.
In other words, having an external journal with a HW RAID setup is a MUST.

Handel is a quick and not-so-dirty ecommerce framework written in Perl. It consists of a set of core modules to do basic cart interactions and order processing via a plugin based pipeline.
While Handel is written to be web agnostic, it does support various different web based languages and framesworks including AxKit, Template Toolkit and Catalyst.
It was started for the conversion of an IIS/ASP based commerce site to Apache/ModPerl, but I decided that is might be useful to others so here it is on CPAN.

1955. A rainbow over the campus of Cal Poly, San Luis Obispo, seems to end on a row of classic 50s cars. The two-tone '53 Olds is nice, but I wish it wasn't obscuring the red-roofed Merc behind it. Shot by my brother, then a freshman there, on 35mm Kodachrome.
Some questions marketers must ask: Does this interaction lead to connections? Do our products support our story? Is the story pulling in numbers that demonstrate that it's working?
In that light, what are you working on? If it's not one of these five, not going to seriously change the dynamic of your marketing, why exactly are you bothering?nullnullnull
