Intelliflush
From EMule Wiki
intellifush is an option Set the filebuffer write flush time in seconds instead of in size.
this is created to prevent that HDD trashing behaviour of the official client... a high filebuffer should always be preferred to keep your HDD healthy... but with the official client you can prevent a chunk that is ready to be uploaded for up to 2 minutes (and with mods this can be even worse) With IntelliFlush you can - in theory - use an unlimited filebuffer without any problems (... only one could be lack of RAM in extreme cases or loss of data in case of a crash).
