comment Why are DNS lookups not respecting /etc/nsswitch.conf & /etc/host.conf?
drsnyder's coworker here: we stumbled on a weird workaround: setting CURLOPT_IPRESOLVE to CURL_IPRESOLVE_V4 avoids the DNS lookup, as demonstrated here: gist.github.com/frankfarmer/360e4bb12ec494ae2d3a

comment How to set up Nginx as a caching reverse proxy?
the cache-buster string idea is great for css/js/images, but it's problematic for HTML. By way of example, you won't see "cache busters" in SO question URLs. The URL of a question page should not change every time someone posts an answer/comment.

comment Is it possible to monitor/gather statistics on DNS lookup timeout rates?
Apparently our host rate-limits DNS requests. It's a bit alarming that a simple 1-request-per-second test was able to trip this limit. This lends itself to answering both of my problems however: we may install our own DNS proxy which we can then (1) monitor and (2) receive reliable service from

comment Is it possible to monitor/gather statistics on DNS lookup timeout rates?
Using nagios. It's looking like we will probably just use something like check_dns to run test queries. I worry, though, that this won't give us much visibility into situations like the current one, where 10% of requests fail.

comment TRIM in centos 5.X?
This is a development server, where we copy/deploy fresh installations of our software for testing several times a day. In the end, this boils down to a cp -r 300megcodedirectory /path/to/depoytarget. It's this cp which is massively underperforming -- it used to take maybe 3 minutes on this box, but has recently degraded to 15 minutes. You mention fragmentation... that's usually not a problem with ext3 is it?

comment TRIM in centos 5.X?
Yeah, there are large number of reasons TRIM won't work for me under normal circumstances (old linux kernel, ext3, vmware), which is why I'm interested in trying to manually TRIM currently unallocated space, if at all possible, with a tool like wiper.sh.

comment TRIM in centos 5.X?
Yes, virtualized. My primary concern is that performance on this system has degraded severely in the last month, even though the configuration hasn't changed in a year. It's being outperformed by systems with 5400 RPM drives at this point.

comment Transfer 10TB of files from USA -> UK datacenter
The difference arises from the OP misstating 11 Mbps when in fact he meant 11 MBps -- which is 8 times faster. BTW, restarting a 10 TB rsync in the case of an interruption will probably take a while, won't it? Hours, or longer?
