You are using a disk-based installation, right? Well, LoadModule needs to load the updated ROM modules into some reset-resident memory. In a worst-case scenario, this is Chip RAM, and yes, access to Chip RAM is slow.
However, you can do the following:
Buy a ROM and install it, thus eliminating the need for replacing ROM modules with RAM modules.
Or, in case your system is equipped with a MMU:
Install the MMULib archive from Aminet and add the following command below SetPatch in the S:Startup-sequence:
MuProtectModules ON REMAP
This will remap the ROM modules from their current location to the fastest available RAM and give you some extra speed. Keep in mind that using this option will occupy RAM which you won’t be able to free.
