Max hash speed
  This is the speed at which DC++ will hash your files, in MiB/s. It is limited by the speed of your disk subsystem, but it can be used to make hashing slower and less noticable. A "normal" hash speed may be anywhere from 20 to 50 MiB/s. (no default)
PM history
  The number of lines that will be read from the private message log and displayed when a new PM is received. (no default)
Mini slot size
  This defines the size of the mini slot. The minimum value for this setting is 64 KiB. (default: 64 KiB)
Max filelist size
  This setting controls the size of the maximum file list that DC++ will open, in mebibytes. This setting helps protect against malformed file lists that require large amounts of memory to decode. You may need to reduce or increase the value of this setting based on personal experience. (default: 512 MiB)
PID
  This is your unique private ID (PID). This will later with an algorithm be used to identify you on ADC hubs. Do not share this with other users.
Auto refresh time
  This controls the interval at which your shared directories are rescanned for new and changed content. This is measured in minutes. (default: 60 minutes)
Write buffer size
  This controls the size of the chunks that DC++ writes to disk for downloads. Measured in kibibytes. (default: 16 KiB)
Auto-search limit
  This will limit the amount of sources a file can have before it will no longer be auto searched for. For example, if this option is set to 2, if a file has more than or exactly 2 sources, the file will be excluded from the auto-search list.
Search history
  Number of old search lines that will be shown in the Search Window. (default: 10)
Bind address
  This setting allows you to bind DC++ to a particular IP address on your machine. Most users do not need to change the default value, 0.0.0.0. However, if you have more than one network interface connected to the internet, you can force DC++ to use a particular connection by entering its IP here. If binding fails, it will do so silently and INADDR_ANY will be used instead. If you experience connection problems make sure that this is set to default. (default: 0.0.0.0)
  This feature requires a restart to be fully effective.
Socket read buffer
  The size of the buffer DC++ use to read sockets. Measured in bytes. (default: 8192 bytes)
Socket write buffer
  The size of the buffer DC++ use to write to sockets. Measured in bytes. (default: 8192 bytes)
