[linux+?] gzip streaming of .zip files tanks performance

[rofl0r]

State your operating system:

Linux gtk2 / cli

DesMuME version

git master

Issue

at least in the game "captain america (u)", using above frontends, the gzip streaming of a .zip archive, which appears to be on-the-fly, heavily affects performance between level section switches, resulting in high cpu load, low fps, and stuttering sound on a mid-level x86 device. using the extracted .nds file instead results in perfect performance. since most NDS games are < 100 mb, it may be better to extract the entire file to ram once on startup instead.
i'm posting this both as a reminder and to hear @zeromus' thoughts, since his absence on IRC makes chatting difficult ;)

zeromus has nothing useful to add for the linux frontend. I'm skeptical that the gzip is done on the fly, otherwise it would be absurdly slow. gzip is not "seekable".
