Horrible Throughput on Licensed Server

Horrible Throughput on Licensed Server

My problem is as follows:


My company is running a licensed version of ELA 9.
We are using a Dedicated Server 2012 Box  with Quad Core Xeon 2.6Ghz Processor with 12G of Ram.
OS is Windows Server 2012 on a 240G Raid 1 SSD Array with a 2T Raid 5 Array for Data (Logs/PgSQL/Archive).

ELA is installed to the OS Drive.

I have set both /bin/run.bat  and /server/conf/wrapper.conf to  2048m minimum and 4096 maximum memory usage for the JVM.

We are monitoring 34 Windows (Server 2008, 2012, Win7) machines (mostly Domain Controllers)

Over the course of the first month of operation we accumulated 36,762 .dat files in the /data directory (each .dat consisting of 2000 logs)  and completely shut down the log analyzer due to it eating all available space on the SSD.  After 5 days of running with all log collection disabled, we are back up and running again.
Within our first 4 hours we are back up to over 600 .dat files.   

What is left to do to improve the performance of ELA so it doesn't fall so far behind so fast?   We cannot afford to shut it down every weekend just so it can catch up.
