So who's still complaining of the lack of s@h PR?
We're now on daily news updates:

We developed hierarchical directory structure to get around the big
directory problem (see August 4, below). This solution is backward
compatible with all current work units. It is being tested in alpha now.
Next week it will go to beta and then to public. We also have a tool to
distribute all recent results into the new hierarchy. When that tool is
run, credit will appear for all of these results. The credit appearance
will be spread over a number of days.
In other news, we have the SnapAppliance 18000 configured. It shows a
10x speed up over the software RAID we are now using. We are awaiting a
UPS for it.

A misconfigured scheduling server ran for about an hour this morning,
misinforming users that they had to upgrade to version 4 of the BOINC
software. This message was in error - please remain with version 3.

We discoverd that the sheer number of files in the upload directory was
killing NFS performance for the file_upload_handler. We started with a
new empty upload directory and the file_upload_handler performed much
better. The rate of connection drops on the upload server dropped to
zero (most of the time). Of course we need to get all those older
results back into play somehow. We are preparing our new SnapAppliance
18000 to host the database. We need to fit it into the power load in our
already fairly full data closet, configure the DB volume, run some
tests, and then copy over the DB files. We will post the progress as we go.

While the project is up and functioning normally, the database and web
servers are overloaded. Because of this you may have noticed difficulty
in transferring work and loading certain web pages. We're tuning these
servers and trying to find the bottlenecks now.

Looks like the servers are quickly getting 'knocked into shape'...
Happy crunchin'
