There still may be with multiboot, but for reasons unrelated to speed. Linux 
installers all seem to think they have an unconditional right to format the 
swap partition. As soon as the second Linux installer formats swap, the 
volume label if present and the UUID are changed, causing first boot of the 
elder Linux to choke on init due to any of different device ID, UUID or label 
for mounting swap. At least when put near the front the device ID is unlikely 
to change when partitioning is extended to accommodate additional Linux

It may be prudent to revisit with modern hardware speeds and software sizes. 
CPU and RAM speeds have advanced considerably more than disk I/O speed in the 
past 17 years, while software bloat is infamous.
