[jboss-jira] [JBoss JIRA] (JGRP-1722) Improve performance of ENCRYPT protocol

[Bela Ban (JIRA)]

    [ https://issues.jboss.org/browse/JGRP-1722?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12948741#comment-12948741 ] 

Bela Ban commented on JGRP-1722:
--------------------------------

Hmm, the biggest chunk of CPU (by far) according to jmc is spent in {{com.sun.crypto.provider.AESCrypt.decryptBlock()}} (30%) and {{com.sun.crypto.provider.AESCrypt.encryptBlock()}} (26%). A total of over 64% is spent in the {{com.sun.crypto.provider}} package !
I'll try to improve other things, but I won't be able to do much about this. Pinging [~NadirX] to take a look; perhaps a different encryption algorithm (or a smaller key size) will help, but I doubt it. Looks like encryption does have a price tage to it...
One thing I'll investigate is whether encryption is done sequentially, using the same cipher, or whether we can parallelize this. If we can, then even a costly encryption / decryption alg won't have much impact.

> A stress tests with the following setup showed that performance (reads and writes/sec) is halved when ENCRYPT protocol is enabled:
> Infinispan had distributed sync cache with 2 owners on 4 nodes, no transactions. The stress test used 10 threads on each node accessing 1024 byte entries, no conflicts on keys, 20 % writes, 80 % reads. 
> It would be great if we could improve the performance of ENCRYPT protocol.
