Title: RE: [ferret_users] Ferret requirements, RAM or CPU?


After having upgraded my RAM (512M to 4G), I can confirm that fact. Increasing the RAM makes a huge difference in terms of computing time (like for regridding). Thanks for your comments.

My colleague Stephen Mulcahy blogged about our recent experience while
regridding with ferret... the process was apparently cpu bound but on
closer investigation this was due to thrashing memory. Increasing the
amount of memory made an incredible differnce. Read about it here:

Kind regards,
