RE: Memory Management
Posted in 2010
Fernando, More memory means you can do more things and yes... 2000 concurrent sessions could be considered small. ;-) With more memory you can do things like in memory database tables for fast response. More memory can be used for advanced processing. (Extensibility that most people don't think of.) Additional things like web services on the same box...

So when you look at a quad core 2 socket... that's 200 PVUs per socket or 400 PVUs. == ~154K for Ultimate Or for Growth ... 50K but you have the memory limitation of 16GB. On a 8 core box 16GB is only 2GB per core... Not a lot when you consider each core has two threads so the machine sees it as 16 virtual cores... The point is that you *can* build out a 2 socket 8 core Linux box for under 5K, under 10K if you load it up on memory, SSDs, etc ... so that single box can support a *lot* of users. So you're going to get killed on the price of the software... Do you need parallel processing? Maybe not. Do you need to go beyond 16GB most likely unless you have a really small system and support a small number of users. Even still 50K is still a lot of money. For understandable reasons I would love to see everybody buy the Ultimate edition... But if the problem is the 16GB limit that you need to re-touch reality... With 16GB of ram for Informix you can support the majority of the systems. Unless of course you call 2000 sessions a small system...
