[php] Composer killed while updating

Unfortuantely composer requires a lot of RAM & processing power. Here are a few things that I did, which combined, made the process bearable. This was on my cloud playpen env.

  1. You may be simply running out of RAM. Enable swap: https://www.digitalocean.com/community/search?q=add+swap (note: I think best practice is to add a seperate partition. Digitalocean's guide is appropriate for their environment)
  2. service mysql stop (kill your DB/mem-hog services to free some RAM - don't forget to start it again!)
  3. use a secondary terminal session running top to watch memory/swap consumption until process is complete.
  4. composer.phar update --prefer-dist -vvv (verbose output [still hangs at some points when working] and use distro zip files). Maybe try a --dry-run too?
  5. Composer is apparently know to run slower in older versions of PHP (e.g. 5.3x). It was still slow in 5.5.9 for me...
