comment Nginx as a reverse proxy and static/dynamic content server at the same time?
You but you would need to run apache on a different port (ex 81) and forward traffic from nginx to apache on port 81. Plenty of info on the nginx site how to do that.

comment How can I use HAproxy with SSL and get X-Forwarded-For headers AND tell PHP that SSL is in use?
If only one of the following would become true a) Nginx gets decent state tracking and fair load balancing b) HAProxy gets decent SSL support One can only hope

comment Software RAID 5 vs RAID 6 performance
@Matt You are correct as disks increase performance would be the same or better. I would say the same because the parity disk is still the bottoleneck.

comment Problem restarting postgres on OS X
It appears I don't have it installed :) that feels stupid. Anyhow you should search for pg_ctl (find / -name pg_ctl as root). Then use that command to start stop it. postgresql.org/docs/8.2/static/app-pg-ctl.html

comment Problem restarting postgres on OS X
Yes but basically you should use pg_ctl to stop start postgres. The weird thing is I just searched for it on my mac and I could not find it.

comment Software RAID 5 vs RAID 6 performance
The benefits of raid 6 are that you do not have any degradation when 1 disk is missing (faulty) degradation starts when 2 disks are missing. It also has better availability than raid5

comment Software RAID 5 vs RAID 6 performance
Write performance of raid 6 with 3 disks would be better than say 4 disks. Generally as you add disks read performance increases and write performance decreases. Each write requires N reads and 2 writes (where N is the number of disks). This is why raid6 and raid5 generally have very poor write performance. Now having a raid6 with 3 disks is pointless due to the wasted disk space obviously.

It is probably worth noting that nginx also can do content caching if you need it. wiki.nginx.org/NginxHttpProxyModule#proxy_cache_path
