We use our ramdisk for special jobs that require some crunching of sales numbers.
We basically copy our monthly sales files (which are distributed by month) into the ramdisk, run the jobs and recreate the partfiles for the month, re-index etc then copy the partfiles and indexes back. We took a weekly job that was taking about 16 hours down to less than 3 hours by doing the work on the ramdisk. btw our SAN is really fast, but the ramdisk is much faster. ________________________________ From: [email protected] [[email protected]] On Behalf Of Augusto Alonso [[email protected]] Sent: Friday, September 03, 2010 10:23 AM To: U2 Users List Subject: Re: [U2] Unidata - Hardware sizing for 550 telnet users Hi Neil. May I ask you: how do you use the Ramdisk? As a temp directory? I'm very interested in improving performance this way...
