Hello,

First of all I would like to thank you for the continuing support and updates, quite exceptional in our world...

At the same time I would like to ask you to consider in the future if there is room for improvement of the TFF demands places on the machine for on a modest hardware it is barely usable.

Following the demise of a G5 dual 2.3 I started to use again an iMac 1GHz with 1.5 GB RAM. With a single window downloading TFF15 CPU usage is around 35 - 45%, real memory around 400 MB, and virtual around 2.2 GB. Unsurprisingly the beach ball spinning appears frequently and everything related to the TFF proceeds very slowly. On a Powerbook 1.67 GHz/ 1GB the behavior is the same though it copes a bit better.

Kind regards,

Ivaylo

    Hello Ivaylo, the CPU usage and memory footprint you describe are normal. Our rendering engine comes from Firefox and is designed to run on much faster machines; Leopard Webkit (the only other more-or-less up-to-date browser for Power Macs these days) has a similar demand for RAM. So the choice is: Live with it, or use an older, more lightweight browser that's incapable to access most modern websites. Or buy a new Mac.

    I can say that I use TFF on my PowerBook 1.67 GHz and it performs decently if you keep in mind that you're using a machine that's 14 years old. My PB has 2 GB of RAM installed, though, and an SSD instead of a spinning HD, and I would recommend this to everyone. I also use TFF on my 800 MHz G3 iBook, which has only 640 MB of RAM (its max. capacity), but also an SSD, so swapping is less of an issue. Finally I use it on my PowerBook G3 400 MHz (Pismo), which is very slow but still usable, it also has 1 GB of RAM, which helps a lot.
