开发过casio dt930的朋友，如果商品信息非常多并且机器非常多的情况下，下载速度慢，是一个问题，本程序，对数据进行了处理，不再添加不必要的空格，另外本程序对数据进行了lzari压缩算法的压缩，在机器内部进行解压缩，由于高估了机器的处理能力，解压缩过程很慢，但对于多台机器来讲，不占机座，比如9台机器3个机座，能缩短1半的时间。-Casio dt930 development have been friends, if the message is more than goods and machinery are many circumstances, slow download speeds, is a problem, the procedures, data processing, not add unnecessary spaces, while the process of data compression algorithm lzari compression, in-house machines extract, due to over-estimated the capacity of the machine, very slow process of decompression, but in terms of multiple machines, do not account for base, such as the 9 machine 3 Block machine can reduce the 1 and a half.
