The CPU time seems correct to me. With multiple threaded VMs the GC takes 25 seconds more CPU time than with single threaded VMs (where it takes 13 seconds). This is probably because there is little parallelism that the GC can exploit (perhaps a small number of very large bignums?).
xactlog’s user interface is rather old-school (the program was originally written in the early 90’s!). Here’s a quick summary of the commands, which you can get with the -? option:
COMMANDS:
keyboard: q -- quit . -- redraw window e -- generate EPS file <program_name>.eps 0..9 -- pass through smoothing filter 'n' times t -- toggle title on/off s -- toggle state logs on/off a -- toggle activity profile on/off p -- toggle percent profile on/off h -- toggle state duration histograms on/off l -- toggle state labels on/off f -- toggle first state only on/off i -- revert to initial display z -- zoom out by factor of 5
mouse: to zoom in, use click&drag to select section of interest to change state ordering, use click&drag on state names to swap states
By the way, your screendump is strange… the middle part, the “percent profile”, should be a summation (put on a scale of 100%) of the activity bars above (one per processor). But the red areas (for the GC) don’t line up… Could you try to run xactlog with the -us or -ms option (to scale to microseconds or milliseconds)?

Gambit has reached a milestone today with the implementation of the parallel garbage collector. This is an important step towards truly concurrent Gambit threads.
When Gambit is configured with --enable-multiple-threaded-vms the available processors will cooperate to do the garbage collection in parallel.
Can we trust what the "time" macro reports? The reported CPU time seems too big. For an example, I have the following example, after
(##gc-report-set! #t)
I get for one routine (refine t) with one thread:

and with multiple vms:

The whole run is listed below.
BTW, what is xactlog supposed to do? It generates a pretty picture for me, but the app doesn't seem to be aware of high resolution screens (at least not on Ubuntu 16.10). And it has a user interface for something?
You may be interested in a screenshot for this job, which I attach. I think the big GCs are for (refine t).
