Hi Experts,

 

          OpenSSL 9.8b. We are facing some performance issues with it. I heard that doing session reuse or using some other ciphers can help improve the performance significantly.

I would like to know -

 

1. Is using the session reuse with ssl handshake is advisable? I read somewhere that session reuse with openssl is controversial with memory usage. It might have some memory leaks. Is that true? What are other issues with ssl session reuse? Does anyone has any numbers on performance gain with session reuse?


 

2. Does changing cipher used improve performance? We use the default one. Is there any numbers on this too? I plan to use one of -

 

SSL_RSA_WITH_3DES_EDE_CBC_SHA
SSL_DH_RSA_WITH_3DES_EDE_CBC_SHA
SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA

TLS_RSA_WITH_3DES_EDE_CBC_SHA
TLS_DH_RSA_WITH_3DES_EDE_CBC_SHA
TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA

TLS_RSA_WITH_AES_128_CBC_SHA
TLS_DH_RSA_WITH_AES_128_CBC_SHA
TLS_DHE_RSA_WITH_AES_128_CBC_SHA

TLS_RSA_WITH_AES_256_CBC_SHA
TLS_DH_RSA_WITH_AES_256_CBC_SHA
TLS_DHE_RSA_WITH_AES_256_CBC_SHA


 

Thanks for your help!

 

Raj....
