Everything looks fine to me.

In fact, your Bits are increasing, normally, from my first post (in this thread) of Bits: -8,425 to currently Bits: -7,915

Cache read misses from an instruction cache generally cause the longest delays because the processor, and in particular the thread of execution, has to wait until the instruction is fetched from main memory.

NAME
pnginfo - display information on the PNG files named SYNOPSIS
pnginfo [-t] [-d] [-D] <filenames> DESCRIPTION
This command dumps information about the PNG files named on the command line. This command's output is based on the output of the tiffinfo command, which is part of the libtiff distribution. Each line output by the command represents a value that has been set within the PNG file. The -t command line option forces pnginfo to use libtiff tiffinfo style lables, instead of the more relevant png names. The -d command line option dumps the bitmap contained by the image to standard out, whilst the -D command merely checks that the image bitmap could be extracted from the file. If nothing is reported by -D, then there was no error. The format for the output bitmaps is hexadecimal, with each pixel presented as a triple -- for instance [red green blue]. This means that paletted images et cetera will have their bitmaps expanded before display. RETURNS
Nothing. EXAMPLE
