15160PTgui -- why doesnt it just use RAM?
- Dec 1, 2007To create a hi-res spherical, PTgui says 7 tiffs at 70MB each requires
about 1GB of scratch disk -- if I have 4 GB of RAM, why does it need a
disk at all except to save the final image? Wouldn't doing everything
in RAM dramatically speed things up, especially since disk I/O seems to
be the bottleneck?
I'm no computer guru, so maybe this is a naive question and I'm missing
What I'm fairly certain of is that in the 5 hours it takes my dual core
2GHz machine (2:30 minutes on Milko's speedtest) to stitch a 16bit
11,000x5500 image, my CPU reads 5-10% most of the time and my disks are
not being accessed much of this time (and could write 1GB a few hundred
times in that time anyway, if that were truly the bottleneck).
