alfred progress time code

regarding rendering with verbosity level 4 / alfred style progress enabled

would someone please explain the render time syntax below. lol.

using my stopwatch the render time was about a minute and a half from my click...

so '1:31.06r' appears to the time in minutes, but why is there an 'r' suffix?

is the suffix r for 'render'? kindof redundant considering the beginning of the line.

how about the other measurements on that 'render time' line

thanks in advance.

example:

Render Time: 9:44.64u 26.77s 1:31.06r
Memory:  441.61 MB of 11.10 GB arena size
    page rclm : 113692	  flts: 0
    # swaps   : 0
    blocks in : 0	   out: 18
    switch ctx: 11	  ictx: 5341224
Peak Geometry Objects: 3

This comes from a C standard and Unix kernels:

ok. perfect. i love this forum.

real is what i was looking for. 'wall clock time'

Real is wall clock time - time from start to finish of the call. This is all elapsed time including time slices used by other processes and time the process spends blocked (for example if it is waiting for I/O to complete).

User is the amount of CPU time spent in user-mode code (outside the kernel) within the process. This is only actual CPU time used in executing the process. Other processes and time the process spends blocked do not count towards this figure.

Sys is the amount of CPU time spent in the kernel within the process. This means executing CPU time spent in system calls within the kernel, as opposed to library code, which is still running in user-space. Like 'user', this is only CPU time used by the process. See below for a brief description of kernel mode (also known as 'supervisor' mode) and the system call mechanism.
