Hi,

Thank you for your answer and sorry for the late,
I have a queue of url:
---------------------------------------
Links =Queue.new
Links.push(url1)
Links.push(url2)
Links.push(url3)

# a method to download page
def openurl(uri)
object_uri = open(url)
end
def ParseHtml(url)
Extract Meta
end

def CommitPage(page)
insert meta to database (Mysql)
end

def Work(url)
openurl(url)
ParseHtml(url)
CommitPage(page)
end


t1=Thread.new{work(url1)}
t2=Thread.new{work(url2)}
t3=Thread.new{work(url3)}
t1.join
t2.join
t3.join
------------------------------------------
The cpu is idle when executing methods openurl, commitpage because they
take time accessing data but I notice that when executing this script
t2 will wait for t1 until it finishes and t3 for t2


have you a solution for this problem, because I am waisting a big time
like this

best regards
