18.5 GDB and GMEM Modes

The main advantage of the GMEM mode is that it is a lot faster than the GDB mode where the application must be monitored by a GDB script. But the GMEM mode is available only for DEC Unix, Linux x86, Solaris (sparc and x86) and Windows 95/98/NT/2000 (x86).

The main advantage of the GDB mode is that it is available on all supported platforms. But it can be very slow if the application does a lot of allocations and deallocations.
