comment Mysql - %CPU load 3000 - random timings
Please, when you have code like that, just update your question. This is impossible to read. Unfortuantelly I have no idea what goes on in your mysqld. I'd probably try straceing the process to see if there is something wrong. Oh and btw. what CPU does it have? 5117% CPU is like 51 cores, is that possible?

What does SHOW PROCESSLIST; return, when under such load?

format config/top output as code to make it readable

comment How can I directly read data from a file in Linux without using the filesystem cache?
@ewwhite You're right. I'd like to hear the explanation. But even if he has a perfect reason, I'm going to tell him to stay away. It's so wrong, I can't even explain.

comment ZFS - Reconnecting a disconnected but fully intact disk
AFAIK when you remove part of a stripe configuration, the whole pool stops working. No reads or writes will work. If you return the disk, it will work again. Removing and reattaching part of redundant vdev should result in resilver.

comment Nginx proxy_pass and redirect
You probably shouldn't make long story short. Quite the opposite. If your upstream is set like upstream blog { ip:8888; } What URL do you enter and what exactly happens (include error message, response code, whatever), or what do you expect to happen?

What do you want the input, output pair be and what it is now? I'm having hard time understanding what are you trying to accomplish.

comment haproxy-varnish can't reach 6k requests
Just a few Qs ... Why HAProxy in front of Varnish? What are the loads during test? How are you testing? Using keep-alives? What hardware? Does the test pass Accept-Encoding: gzip? What is the cache hit rate?

comment Optimize Linux file system for reading ~500M small files
If it's just a file sharing, I'd go with FreeBSD/ZFS, or something Illumos based and a huge amount of memory. Maybe SSD for L2ARC.

comment How does HA / failover work?
"how to provide HA of that load balancer?", that's what I'm talking about at the end of my answer. It is easy to set up Active/Passive (VRRP) solution for 2-nodes with low load. It gets much more tricky with 10 nodes. Especially if you do not want asymmetric load.
