A technician uses an old SSL server due to budget constraints and discovers performance degrades dramatically after enabling PFS. The technician cannot determine why performance degraded so…

ECC reduces computational overhead compared to RSA and would improve, not degrade, PFS performance.

PFS requires ephemeral key generation on every session, and DHE-RSA achieves this using large RSA key moduli with expensive modular exponentiation operations. Older servers lacking hardware crypto acceleration must perform these operations entirely in software, causing dramatic throughput drops. Newer servers typically default to ECDHE, which achieves equivalent PFS security with far lower computational cost due to smaller key sizes in elliptic curve math.

Disk size has no bearing on SSL/TLS handshake cryptographic operations or key exchange performance.

Memory size affects concurrent session capacity but does not drive per-handshake cryptographic overhead.

Decryption chips (hardware acceleration) would speed up cryptographic operations and reduce degradation, not cause it.

Connection request volume is a load metric and not a configurable option that explains the underlying cryptographic performance bottleneck.
