Tilman Hausherr commented on PDFBOX-4253:
-----------------------------------------
Yes this is a known flaw, but it has existed before, see functionsArray. That
one is cached as well. If there is ever a tool that allows to change live COS
structures and render immediately, then we'd have to adjust this.

> I ran the profiler on PDFJS-9770-slow.pdf and it turned out that a few
> seconds were lost in {{COSArray.toFloatArray()}}. Caching it saves about 30%.
