Opened: Mar 15, 2018
Severity: 4-Minor


DEFLATE/gzip compression levels other than level 1 bypass the hardware accelerator and are serviced in software, resulting in higher CPU utilization and slower compression times.


Compression requests serviced by software are scheduled on local CPUs. During heavy compression traffic, overall system traffic flow may be reduced. Compression requests serviced in software may take significantly longer to complete.


-- Compression requests for DEFLATE/gzip levels other than level 1. -- BIG-IP devices using Cave Creek SSL hardware acceleration.



Fix Information

Hardware accelerator correctly registers for all DEFLATE/gzip compression levels, not just level 1.
