BitComet is a p2p file-sharing freeware fully compatible with BitTorrent, which is one of the most popular p2p protocol designed for high-speed distribution of 100MB or GB sized files. BitComet is a powerful, clean, fast, and easy-to-use bittorrent client.
The core of BitComet is completely written in C++ (STL), one of the most efficient languages. This makes it quite different from the original client (written in python), and those written in java or other language. The development of BitComet began in Aug, 2003. After more than two year hard work, now the core is stable and fast with very low CPU usage. It is reported that it can even working smoothly on AMD K6 266MHz MMX with 128M RAM.
BitComet is designed for multiple simultaneous downloads. Because the efficiency of the core, it can run a lot of task simultaneously. It is reported by a site administrator that it runs well when having 100+ simultaneous uploading tasks. Moreover, you can even select download files in one torrent and set download priority for them.
The function of Intelligent Disk Cache is once an important reason why people choose BitComet. It is designed for fast downloaders. When uploads or download rate exceeds 500kB/s or even more than 1MB/s, a carefully designed disk cache mechanism in BitComet will greatly improved the hard-disk performance by decrease the read and write frequency of your hard disk. So that the life time of hard disk can be longer. Some statistics of the operation of the cache is avaliable in the Log View, e.g. HitRatio, Read/Write Requrest Frequence, Actual Disk Read/Write Frequence, where one can easiliy find out the improvement.
Another advanced function regarding to disk performance is Intelligent Disk Allocating. BitComet never make time-consuming disk allocation as some of other client also does. The difference is BitComet does not allocate disk space little by little, it allocate space by blocks in a reserved space. As a result, BitComet can decrease the disk fragment caused by downloading to almost zero.
