Hello,

I am using Nutch 0.5 and am wondering whether anyone noticed that
fetcher sometimes continuously slows down, from the moment it was
started?

I am using 10 threads, and I noticed that the fetcher started with
about 100KB/second, went up to 200kb/second, and then the crawling rate
started continously going down. After half a day it was crawling at a
rate of 30KB/second.  The fetch list consists of a number of random
hosts, so I don't think this should be caused by the delay between
requests to the the host.  There was no other netowork traffic on my
server.  Of course, there could be something external to my machine and
network card, but I couldn't check that.

Has anyone seen this with Nutch?  Should I suspect Nutch, or something
local to my installation or even external to my machine?

Thanks,
Otis
