Firefox config that supposedly has less load on CPU?

There is an old thread during development of SeaMonkey browser discussing about these two settings in about:config that supposedly cuts CPU load by a notable margin:

network.buffer.cache.count = 128
network.buffer.cache.size = 262144

128x262144 Bytes=32 MB of buffer
