Sizing for SSL
Chapter 4 Hardware Sizing 95
Although hardware accelerator cards cannot eliminate the impact of using SSL,
they can improve performance significantly comparedwith software-based
implementation. Sun ONE Directory Server 5.2 supports the use of SSL hardware
accelerators such as supported Sun Crypto Accelerator hardware.
Using a Sun Crypto Accelerator board can be useful when SSL key calculation is a
bottleneck. Such hardware may not improve performance when SSL key
calculation is not a bottleneck, however, as it specifically accelerates key
calculations during the SSL handshake to negotiate the connection, but not
encryptionand decryption of messages thereafter. Refer to Appendix B, “Using the
Sun Crypto Accelerator Board,” for instructions on using such hardware with a
Directory Server instance.
