Time to reset caches (compile Boost) recently became 3x slower

Use boost theme Purge caches VERIFY: css is recreated and moodle is styled Change a boost setting such as brand colour VERIFY: css is changed and the look of site has changed VERIFY Using curl or the web inspector, examine the time to compile the scss before and after the patch and that with the patch, peformance is dramatically improved. For example, using curl, you can use styles_debug to do this: curl -s -w "\nConnect time: %{time_connect} Time to first byte: %{time_starttransfer} Total time: %{time_total} \n" -o /dev/null 'http://[YOUMOODLE]/theme/styles_debug.php?theme=boost&type=scss' Ensure that css is flipped when in an RTL language

Edit /theme/boost/scss/moodle.scss Move the following lines at the END of the file // Import font awesome. @import "fontawesome/moodle-path"; @import "fontawesome/font-awesome"; Save and done. On my system, the compile goes from taking about 16s, to 7.5s.
