The 68LC040 was very fast compared to the 68030, and even floating-point operations performed through emulation ran at a decent speed compared to the older machine. Not nearly as fast as on a 68040, but quite fast.

The biggest problem if you owned a Macintosh LC with this processor was Microsoft. When the very first Macintosh with a coprocessor was released, they added support in Excel by checking "does this computer have a 68020 processor". Which obviously failed when the next Mac had a 68030 processor. Which is _not_ a 68020. So they changed to "does this computer have a 68020 or higher processor". Which made Excel crash on the 68LC040. What made this particularly infurating was that the same operating system call returned _both_ the CPU model _and_ the FPU model, so all they had to check was whether the computer had an FPU.
