I have a loop:

Dir.new("#{RAILS\_ROOT}/public/images/vehicles/uploaded/  
#{@vehicle.id}").each do |image|  
if image =~ /.\*.jpg$/i  
@vehicle\_image = VehicleImage.new()  
@vehicle.vehicle\_images \<\< @vehicle\_image  
File.cp("#{RAILS\_ROOT}/public/images/vehicles/uploaded/  
#{@vehicle.id}/#{image}", “#{RAILS\_ROOT}/public/images/vehicles/  
original/#{@vehicle\_image.id}.jpg”)  
MiddleMan.new\_worker(:class =\> :resizeimage\_worker, :args =\>  
{:id =\> @vehicle\_image.id, :basepath =\> “#{RAILS\_ROOT}/public/images/  
vehicles/”})  
end  
end

It appears to be waiting for MiddleMan.new\_worker to return before  
continuing to the next iteration.  
Im sure I must be doing something wrong here - as this would defeat  
the whole point of backgroundrb?

Any thoughts?

Kind Regards,

Matt Williams

Thank you kindly for the quick reply.

It turns out I spawning new workers for each image, each of which  
consumed crazy amounts of resources and gave the illusion of blocking  
as the system was running so slow
