Something which is definately a "good to know" when using the backend. I installed it and published to header without issues.
To answer the query below. Load averages are UNIX averages for servers. They are shown through the "uptime" command ((or others like "top").
The values represent the amount of "load" on the server ie:
last 1 minute : last 5 minutes : last 15 minutes
Load averages are *NOT* measures of cpu usage, although cpu load does play a factor in the measurement. The values represent the load on a server and this includes cpu, io, vm, etc.
A server that is lightly loaded, will sit between values of 0 - 1.
A server with heavy load will be above 1 and could go to 90 (very rare but I have seen it happen). Any values between 5 and 10 normally get sluggish responses (depends on the OS of course).
If your load average is consistently above 1 however, that means the server is very busy alot of the time and you may need to performance tune apps, server, or get a better server.
