Greetings All!
Currently we compile our software with (gcc version 4.1.2 20080704 (Red Hat
4.1.2-44)) which comes standard on CentOS 5.4-x86_64. We're all straight
C/C++ but we do a lot with X11/Xm/Xt (including some really, really
old-school IPC with Xfunnels!)
Deploying our software on the previous generation of Dell Precision T5500
workstations (from last week) with whatever current BIOS version the box
comes with is pig slow. So, we'd downgrade the BIOS to Dell's A02 from last
year and life was good, all our software ran as it should.
Fast forward a week and Dell has changed the processor in these boxes along
with the motherboard and BIOS revision (still calling it a T5500) and we're
in a predicament. We can't downgrade the BIOS anymore, it'll brick the box
and our software is once again pig slow.
So my question to the experts is... Would upgrading to a more current
compiler possibly get me any better performance??? As in taking advantage
of the newer hardware, bios, dma, magic bus, etc??? Or, is the the compiler
I'm using new enough that I should be looking other places for my hang
ups???
Thanks,
