• Latency in Sending and Receiving Files From Amazon EC2 - Justification

  - by Adroidist

  I am facing a huge delay while uploading and downloading files from my Windows Amazon EC2 server to my android device. It takes around 50 seconds to upload then download 500 Kbytes image. My location is in asia and the server is is US-East. I pinged the server from my android and obtained values around 500 ms for RTT. Is this normal? How is this explained? I tried this website: http://cloudharmony.com/speedtest/run and obtained that downloading 270 Kbytes file takes around 20 seconds. How is this delay justified?

• Public DNS Server fails on Windows Amazon EC2

  - by Adroidist

  I have started a new Windows server instance on Amazon EC2. The security group has the following rules: Ports Protocol Source 22 tcp 0.0.0.0/0 80 tcp 0.0.0.0/0 443 tcp 0.0.0.0/0 3389 tcp 0.0.0.0/0 53 udp 0.0.0.0/0 -1 icmp 0.0.0.0/0 I am able to ping the public DNS server of the machine and i can connect to it using Windows Remote Desktop connection. However, when i put in my web browser the public DNS server, it fails to connect. Morever, I used filezilla and putty (and in both I loaded the private key .pem) but i receive connection timed out. I disabled the firewall on both my pc and the instance (which I entered using Remote desktop connection). Can you please tell me what I am missing?

• Justification of Amazon EC2 Performance

  - by Adroidist

  I have a .jar file that represents a server which receives over TCP an image in bytes (of size at most 500 kb) and writes it file. It then sobels this image and sends it over TCP socket to the client side. I ran it on my laptop and it was very fast. But when I put it on Amazon EC2 server m1.large instance, i found out it is very slow - around 10 times slower. It might be the inefficiency in the code algorithm but in fact my code is nothing but receive image (like any byte file) run the sobel algorithm and send. I have the following questions: 1- Is it normal performance of Amazon EC2 server- I have read the following links link1 and link2 2- Even if the code is not that efficient, the server is finally handling a very low load (just one client), does the "inefficient" code justify such performance? 3- My laptop is dual core only...Why would the amazon ec2 server have worse performance that my laptop? How is this explained? Excuse me for my ignorance.
