We did not use ram disk software. Howie never brought it up, so we did not experiment with it. Here are the six factors determining performance of the POST module:
1. Size of the email � (assume 10k html for calculations.) 2. Tokens � Passing variables into the email. 3. MX Servers on the other end. 4. Size of the Queue 5. Server Hardware and Software Setup 6. Bandwidth I would ask Howie to put these in order of importance and anyone on the list to provide input. Server hardware was dual processor, 2 Gig. RAM, Adaptec wide, Seagate 10k rpm Cheetah 18 gig drive. Server software was Win2k Advance Server (don�t know if this made a difference), with one 2 gig. Partition for OS , 16 for database, Ims Out and Ims logs folders. No RAID setup. Applications were CF Ent. 5, MSSQL 7, IMS POST. (Howie said it was better to run the SQL on the same machine. Don't know why?) Lan was 100 meg. Switch to Cisco 4500 and WAN was DS-3 a few hops from Uunet�s backbone. We had two Linux DNS servers on the same subnet and set 8 more in IMS Config. on tier 1 backbone. More later�� Regards to all, DGo -----Original Message----- From: John Wright [mailto:[EMAIL PROTECTED] Sent: Thursday, April 01, 2004 10:22 AM To: inFusion Support List Subject: [iMS] RAMDisk results I installed and tested the RAMDisk mentioned in an earlier thread with disappointing results. I configured the RAMDisk to hold the POST spool directory. While I did see a slight performance increase for creating files with CFX_iMSMail, the net improvement in my overall sending speed was marginal. Also, after sending about 1 million emails my server locked-up with some odd memory related errors in the event log. I have removed the RAMDisk from my server. I have tried several approaches now to increase the rate at which iMS POST will send emails. No matter what I try, it seems like 23K-24K per hour is the limit. We would like to double this rate to around 50K/hour. Has anyone achieved this speed from a single server? If so, how? Note that we send unique emails that average about 15KB in size. We have no bandwidth restrictions. We have the full enterprise version (1024 threads). Thanks.
