:) In nearly every system I've measured since the year 2000 (when I started recording such information), converting ALL the database files to SSD (RAM disks) would make less than a 5% response time improvement to almost everyone using the system.

Oracle - Performance Not that many years ago the rage of the day was ram disks which promised the performance of RAM in your disk subsystem. Got to play around with one for a bit & I'll agree that they made Oracle scream such that PIO was no longer a problem. Wonder if that conforms to the idea of a in-memory DB?

Oracle - Performance How does timesten compare with Oracle Database in performance, availability etc? Timesten in-memory Database - a brief :- The database system needs an inexpensive, plentiful memory, and the dramatic increases in processor speeds relative to the modest increases in disk drive performance.TimesTen produces software that brings real-time database performance to applications. With TimesTen In-Memory Database Technology,throughput is measured in tens of thousands of operations per second, and response times are counted in microseconds. Though internally unique, TimesTen's products are accessed through standards-based interfaces, and designed for easy integration into existing software infrastructures. ---------------------------------------------------------------- Please see the official ORACLE-L FAQ: http://www.orafaq.com ---------------------------------------------------------------- To unsubscribe send email to: oracle-l-request@xxxxxxxxxxxxx put 'unsubscribe' in the subject line. -- Archives are at //www.freelists.org/archives/oracle-l/ FAQ is at //www.freelists.org/help/fom-serve/cache/1.html ----------------------------------------------------------------- ---------------------------------------------------------------- Please see the official ORACLE-L FAQ: http://www.orafaq.com ---------------------------------------------------------------- To unsubscribe send email to: oracle-l-request@xxxxxxxxxxxxx put 'unsubscribe' in the subject line. -- Archives are at //www.freelists.org/archives/oracle-l/ FAQ is at //www.freelists.org/help/fom-serve/cache/1.html ----------------------------------------------------------------- ---------------------------------------------------------------- Please see the official ORACLE-L FAQ: http://www.orafaq.com ---------------------------------------------------------------- To unsubscribe send email to: oracle-l-request@xxxxxxxxxxxxx put 'unsubscribe' in the subject line. -- Archives are at //www.freelists.org/archives/oracle-l/ FAQ is at //www.freelists.org/help/fom-serve/cache/1.html -----------------------------------------------------------------
