Re: Cpu Usage cozsftp
Co:Z SFTP itself doesn't use much CPU, but it uses IBM OpenSSH which does use a lot of CPU.
You can reduce the CPU of IBM OpenSSH dramatically by using z Architecture CPACF accelerated cipher and mac algorithms, since this is where the large majority of the CPU is consumed.
See one of our "OpenSSH Quick Install Guides" (depending on the version of IBM z/OS OpenSSH that you are using) for detailed tuning information:

Note: Co:Z Gold Enterprise License and Support customers receive at no charge our "Co:Z SFTP Up and Running" service where we work with your technical team to configure, tune, and verify IBM OpenSSH.
