TM1 Forum

I was wondering if anyone has had a chance to put TM1 on a newer box that has maybe the new Intel Nahalem processors with DDR3 memory or similar. Did you see a startup time decrease? I know TM1 is loaded into memory and was wondering if hardware would be that big of a factor.

Thanks!

While the information is pre-loaded into RAM during startup, the calcs and feeders must be worked out by the processors before they can be put in RAM. As a result you will notice performance changes depending on both your CPU and RAM setups.

Well here's my recent experience...

Our dev and prod machines are both both dual X5570's (Nahalem generation). We were running 128GB in both until I saw that the memory rate was only at 800Mhz when I knew the processor and board were capable of 1333Mhz. Turns out that on DL380 G6 Proliants, if you want to run at 1333Mhz, you can't have the third channel populated.

So, eagarly hoping to lower our 55 minute startup (and 30-40 minute, lockout security refreshes on security property changes), I dropped the ram to 96GB (8x12) and bumped the speed in the bios up to 1333Mhz. The result was disappointing (at least for server startup)... there was zero change -- still at 55 minutes. Our startup is limited to only 1 thread so perhaps things might have been different with more threads.

That said, things (websheets in particular) do seem a little snappier but I really can't point to the memory speed increase as a definitive improvement for end users or for tm1 processes.
