From a Crucial Insider email:

Upgrading Memory Dramatically Improves Performance

New tests conducted by VeriTest reveal just how dramatic the improvements can be. VeriTest measured the performance improvement of a Web server as they increased the amount of RAM in the system from 512MB to 2GB and 4GB.

The results showed that with each upgrade in the amount of RAM in a Web server, the performance levels increased significantly in both data throughput and the number of Web requests per second the server was able to handle. When the amount of RAM was increased from 512MB to 2GB, the data throughput performance and number of Web requests per second doubled. When the amount of RAM was upgraded to 4GB, performance levels increased by tenfold over the results using 512MB of RAM. In comparing the 2GB to 4GB RAM configurations, the Web server data throughput and number of Web requests per second increased by a factor of five.

The tests were conducted on a Dell server but the results are interesting. k

October 20 - 14:41 EDT¬?¬? The Swinburne University of Technology's Center for Astrophysics and Supercomputing in Australia has implemented Apple Xserve RAID storage systems for use with its 130-node Dell cluster.

"We looked at upgrading the supercomputer but that would have been too expensive for what we needed," the center's director, Professor Matthew Bailes, told LinuxWorld. "Although we don't have much to do with Apple, after seeing its new Xserve RAID storage device we decided to evaluate it... The Xserve RAID is the cheapest system of its type and none of the other mainstream players have a comparable price. Also, at around 100Mbps read and write to disk, it is faster than our SCSI system which has an I/O of 50Mbps."

The center purchased six Xserve RAID systems with a combined storage capacity of 13.2TB for "around AUD$100,000 including education and volume discounts."
