While there are performance improvements in AR System 7.5.00 (and even more in AR System 7.6.0x), just wanted to clarify that 32-bit vs. 64-bit does not necessarily lead to a performance increase unless you are running out of memory on a constant basis. There's actually a small decrease in performance of 64-bit vs. 32-bit due to a bit more overhead in process/memory management. However, if you are running out of memory then you could see a performance increase since your cache can be bigger and thus you'd not be swapping/paging to disk so often. The increase in available memory also can result in more stability. So by all means, I would consider upgrading. Just wanted to ensure that your reasons for doing so were clearer. -David J.

Hi all, Greetings to all, I have recently joined ARS list and have been working on AR server since about 2 and a half years as a developer in BMC software. Now I have an interesting challenge in front of me I need to upgrade an ARS 5.0.1 to ARS 7.5 P003. The reason being performance hit on HP UX machine due to high number of concurrent users. So here is my problem I am not sure that if we upgrade to ARS 7.5 P008 there will be an performance improvement, but as far as I know I am betting on 64-bit support of ARS 7.5 as compared to ARS 5.0.1 which is 32-bit. Also number of memory leaks that have been fixed along the version. So if anyone thinks that this is a good idea to go ahead with let me know. Also I am currently investigating on the correct and accurate steps to perform the upgrade. If anyone had already performed the upgrade before kindly share the experience as it will be a great help. Just to give a environment info we are on ARS 5.0.1 on HP-UX machine with no OOTB apps installed at all. But have a completely customized application developed on this server which we use.
