GWT中的大量数据处理

Question

I am having a bunch of records (approx 10k) and need to be encrypted at the client side and then traverse over the network with RPC call . The Encryption process and traversing to server takes long time for 10k records. Is there any way so that the time can be reduced.

Time for Encryption takes : 1:10 Minutes Time for sending and receiving back the 10k records from Client to Server and Server to Client takes : 3:46 Minutes

Server is on GoDaddy - US and am accessing from India. Client machine Configuration : Currently 4GB Memory (which may be less in real time , might be 1GB or 2GB) Server Machine Configuration: 4GB

Encryption is done at client side only.

The Java Objects are being traversed in List and Map Collections.

Answer 1

尝试运行而不需要调试，看看需要多长时间。

Answer 2

Well here are some thoughts:

Speeding up client-side encryption :

Are you using a 3rd party library to do encryption? I don't think you will be able to improve this much with Javascript. You could look for another library which might be faster.

However you might also look into Native Client .
This allows you to run C/C++ code in the Chrome sandbox with nearly native speed. However right now it only works in the latest Chrome versions.

You could have the JS encryption library as a fallback for all other browsers (Firefox, Safari, IE)

Speeding up sending to backend/server

I can only think of using some kind of client side compression library to compress the encrypted 10k records before sending it to the server.
