I think EM is overkill here. The following example uses PUT not POST,
but I'm sure you'll be able to adapt it.

require 'net/http'
require 'uri'

# Configuration variables:
THREAD_COUNT = 10
REQUESTS_PER_THREAD = 10
FILENAME = 'file_to_put'
URL = 'http://localhost/DropBox/file_to_put'

# Put a data string to the specified url:
def urlput(url, data)
    begin
        uri = URI.parse(url)
        response = nil
        value = nil
        Net::HTTP.start(uri.host) { |http|
            response, value = http.put(uri.path, data, nil)
        }
        p response.message if (response.code.to_i >= 300)
    rescue => e
        p e
    end
    value
end

# Read the file to put:
data = File.new(FILENAME).read

start = Time.now
$threads = []
(1..THREAD_COUNT).each {|thread|
    $threads << Thread.new(thread) { |thread_no|
        (1..REQUESTS_PER_THREAD).each {
            urlput(URL, data)
        }
    }
}
$threads.each { |aThread| aThread.join }
puts "#{THREAD_COUNT*REQUESTS_PER_THREAD} requests completed in #{Time.now - start} seconds"
