When I simply "sdfopen" the first file and plot the first variable/first time/first level, I get my result essentially immediately. When I instead "xdfopen" the data descriptor file and try to plot the same, it takes some time (~10 sec) to plot. When I repeat the same sort of thing but operate on several times the difference in performance between the two methods is of course very noticeable.</div><div><br></div><div>The issue seems to be in the "options template" line below; taking that out and explicitly putting the first file in I can "xdfopen" the data descriptor file and plot the first variable essentially instantly. Additional metadata in the data descriptor file (e.g., from make_ctl.sh) does not help or matter as far as I can tell.</div><div><br></div><div>Can anyone suggest a solution to this problem?
