Default 64 bit question

We have few 64 bit servers and 32 bit servers. We didn't find any performance difference on 64 bit boxes and 32 bit boxes. Are we missing some thing here? Our applications use mostly 2-3 gb ram. If we use more than 4 GB, would it show the difference performance?

I not sure if you are supposed to be able to see a significant change in the system's performance. Do you have a 64bit operation system on the server?

I do know that some application run better on 64bit server and other applications run only on 64bit servers.

We also recently bought 64bit servers to install exchange 2007 and they have been performing really well.

Well they aren't designed to show a lot of variation. The 64 bit can generally take more on and is more reliable, so if you were making a choice, i would go with the 64 bit servers.

By simply upgrading the OS to 64 bit you might not see a performance increase. First understand a 64 bit OS simply allows a 64 bit application to address more then 4GB previously 32bit's limit. So if your application are not addressing the larger RAM you will not see an increase in performance.

Hi Tom,

If you have (PAE) Physical Address Extension, then you can use more than 4GB and will see the performance.

Whity,

If I'm wrong correct me.


Thanks,
David K.

By all means if you can get 64 bit servers go to them. Even if they are not showing performance benefits now, they will in the future. Plus they can access more than 4 GB of RAM as well.

Well they may not be developed to demonstrate a lot of difference. The 64 bit can usually take more on and is more efficient, so if you were creating an option, i would go with the 64 bit web servers.

You will get increase in performance if you use 64bit OS and more than 4GB ram installed on server.
