| 03:47.39 | DTRemenak | blast007: how much of that is due to the use of deflate and Z_RLE instead of compress2 and Z_DEFAULT_STRATEGY? and how do the resulting file sizes compare? |

| 10:17.03 | blast007 | DTRemenak: resulting sizes are pretty close. Just took a screenshot of the menu at 1440p with 2.4.10 and this code. 2.4.10 was 1541KB and the new stuff was 1623KB. |
| 10:17.37 | blast007 | the new stuff also uses a zlib compression level of 6 instead of 9 since it really didn't compress much better |
| 10:23.02 | blast007 | going from 6 to 9 only shaved off like 56 bytes in that 1440p menu test |
| 10:24.12 | blast007 | using Z_DEFAULT_STRATEGY was a lot slower, starting out at around 550ms with compression level of 6 and starting at almost 5 seconds with compression level of 9 |
| 10:25.22 | blast007 | so, main speed difference was using Z_RLE |

| 16:19.27 | DTRemenak | blast007: cool. that lines up pretty well with my expectations. Z_RLE is good stuff for PNG. Couldn't use it at the time...RH/Debian stable didn't have new enough zlib. |
