A "Linux systems specialist", did claim my previous business card and did so from 2001 to May 2013. Now it says "Senior System Administrator" in another company, Stonesoft, which is part of McAfee/Intel Security.

My heart also has a place for FreeBSD.

comment Ubuntu Server 14.04LTS Swappiness for server with 16GB memory
Higher swappiness causes rarely used processes to be swapped to disk very early, so they won't use the precious RAM. If they would use RAM unnecessarily with the low swappiness value, the server would be swapping much more whenever the memory pressure hits because it would have to swap the idle processes out of the way.

Keeping stuff in memory is much faster than load it again from the disk. Don't be afraid of the amount of used memory, free RAM is wasted RAM. Linux is very smart in its memory use.

Uh, yeah, snmptrapd receives the traps. Anyway the snmptrap is just a client program.

comment VPS Unknown Read/Write
I guess you have way too many httpd processes configured and if there's a database server running on the same host, too, then the one gig of RAM is not very much as we can see from the swap usage. Or, then it's just bad code. That's all the magic we can use right now here.

comment how to do synchronization with multiple servers?
Many of those "enterprise cluster file systems" suck donkey balls whenever your filesystem contains (tens of) millions of small files, they start spending all the time just synchronizing the state and the performance drop is abysmal. Just a warning.
