SSH CLI -v (console output) option causes high master CPU utilization

XMLWordPrintable

      I trigger a lot of builds remotely using SSH based client. We use the "-s -v -w -r 5" command line options.

      When -v is enabled, the SSH command thread running in the master uses a LOT of CPU. As in a full CPU core. When -v is not enabled this thread does not use any CPU.
