I would not have expected it to impact load times significantly unless
you were pulling web pages from a very fast local web server.

Polling every 10ms is probably capable of dealing with all the data a
home internet link is capable of delivering

The fdset function will mainly improve responsiveness as NetSurf does
not need to poll the fetchers unecessarily. On slow connections
instead of polling the fetchers 100 times a second for data that
simply has not arrived yet it will instead only use processor when
data is available to process.

we should update those then ;-)

fyi GTK port on my laptop (at work with 200Mbit) connection completes
news.bbc.co.uk in 0.8s using fdset, and 1.9s using polled (no cache)

Thats exactly what it will be doing, if there is any to spare ;-)
