Add a filesystem-cache-flush command from Yee to try to increase the statistics: 100 jobs of each type (crowdstrike on/off).  Run only one crowdstrike_on job and one crowdstrike_off job at a time to avoid leaning too heavily on the filesystem.  Unfortunately this means all the "on" jobs ran on sdfrome007 (100 jobs)  and all the "off" jobs ran on sdfrome039 (34 jobs) sdfrome037 (25 jobs) sdfrome042 (30 39 jobs) and sdfrome087 (2 jobs).  The first "on" job time was 133 second (slurm job id 42810224) and the first "off" job time was 119 seconds.  This looks pretty consistent with the distribution of all job times (see plot below) suggesting that data caching wasn't a bit effect since adding Yee's cache-flush command (previously some jobs ran as quickly at 90 seconds).
