Revisiting development environment
So running Aptana through a JRE via USB which also hosts the SVN and apache/mysql/ftp servers turned out not so great.
I’ve removed Aptana and the JRE from the flash drive.
Aptana now needs to be installed and configured (just once) on whichever machine I’m using to develop on (usually my desktop and laptop).
It will now only host the XAMPP setup and Aptana workspace files.
XAMPP’s servers aren’t really affected by the “slow” USB flash drive, and once Aptana loads its workspace files they stay in RAM from what I can tell.
