what are the typical types of jobs you are running?
Firefly is rather economical so for most types of calculations
2 GB of RAM is more than enough. How do you set the memory/mwords
keywords in the input file? Do you run check run before the actual
run of Firefly to get proper memory settings?

Kind regards,

>Dear Sir,
>This is in regard to the use of Firefly8 on Windows7. My laptop has 2Gb DDR3 RAM with i3 2 GHz processor. The other day I was running a program and it almost reached the peak RAM usage of 1.9 Gb. So I increased the virtual memory to be 8Gb in which 2Gb alone for FIREFLY8 installed partition. But I was surprised not to find any effects on the program..As the CPU % would go to zero and RAM usage then goes down. After that again CPU % goes up and RAM usage again rises. So is there any way I can use virtual memory to compensate for the shortage of RAM? If yes, how do  do it? Also I found WinXP to be better in this regard. Please help.
