I've been looking at the organisation of my project trying to trim down it's size a touch... and libvorbis, is really the only think bigger than 100k coming in at over 1 meg .dll I've been looking through the code for vorbis_enc as that's the object file taking 95% of the space, and i can't figure out why it is so damn big... there's only a few thousand lines of code there

...le as dynamic loadable content. After I studied the linker map output and saw what are the minimal requirements of the dynamic linker itself from the C library (the object files grabbed by the linker at symbol resolution, from the archive file), I managed to reduce the size of the COM32 module from 34K to 25K. In those 25K, however, I also left a small part of the C library that I considered to be likely required by future dynamic modules, which would link against the root module services. Without this additional code, the minimal size of the module would have been 15K (so there currently is appr...

Good morning Gluster users, I'm very new to the Gluster file system. My apologies if this is not the correct way to seek assistance. However, I would appreciate some insight into understanding the issue I have. I have three nodes running two volumes, engine and data. The third node is the arbiter on both volumes. Both volumes were operation fine but one of the volumes, data, no longer
