Error description
The communication part of an SSL connected session can be significantly more time consuming than what can be justified by extra encryption/decryption compute time. For a communication intense workload a performance loss of up to 50% has been observed. One symptom of hitting this problem would be 'ready' threads (onstat -g rea) in a system that's not otherwise suffering from cpu shortage. Those 'ready' states could occur with sqlexec threads on both cpu and encrypt VPs, affected threads' stacks would contain calls to ssl_encrypt_bind() or ssl_encrypt_unbind().
