Processor power

know if Eagle has or will have a 64 bit version? I looked on the cadsoft

Thanks

Thanks for the suggestions

I had some machines with windows-xp and 4GB RAM. It turned out that win

can not manage well the adresses above 3GB where some BIOS, graphic, I/O

etc. is located. Reducing RAM to 3GB turned the PC's into well running

machines. Give it a try, cost nothing

Your issue / question comes up regularly and always pertains to autorouting.

Search the older posts for a number of conditions that cause long route

times.

BGA's, component spacing, inconsiderate manual routing and the big hitter,

the routing grid.

If you can double the grid to 2mil the time should divide by 4 to 3 hours

and possibly less.

See some of the times mentioned in earlier posts.

I hope this points you in the right direction

What I have gathered from the newsgroups and i could be wrong.

Eagle can only use 1 core for routing as you can't do parallel process

of that process. A second core would support the OS.

I don't think the display update process is done on a different core

either. The redraw while running is not too much overhead unless you

have a video card without a GPU

On the hardware.

CPU with large L3 and L2 cache and high clock (HT) and buss speed. 4

cores and slower clock will be slower 2 cores and faster clock.

I am guessing you are running DDR2 at 533Mh or 800Mhz. With DDR3 it

looks like you can get to 1800Mhz. With that I would think you would get

2 to 4 time faster depending on how much you pay to get the fastest CPU

and Memory available.

I don't know if anybody had benchmarked XP vs Linux on autorouting time.
