comment which CDNs are popular websites using?
Great info, thanks. I see that MaxCDN list stackoverflow as a customer on their frontpage - wonder if that's still the case?

comment Is this a sensible way to scale Nginx for static content serving?
I see - good to know, thank you! I was really hoping to avoid having to have the application servers aware of the number/configuration of nginx servers and doing multiple operations (e.g. having to handle situation where one PUT fails). Regarding resyncs - you mean using rsync? Might it be viable just to update one server and have rsync deal with propagation after each file put?

comment Is my VPS server secure? Steps needed to make it secure, if not?
Yeah the linode library has a lot of good stuff in it. IMO though some of these security recommendations are a bit pointless when the Linode admin tool (which gives access to everything) does not implement them (pure username/password).

comment Is Zabbix the right tool for me?
I was under the impression that Zabbix can use SNMP - not so?

what number of workers would be appropriate for many very small files? More than the number of CPU cores?

comment HAProxy being killed with more that 54,000 connections
@WillyTarreau - could you point us to any information about how TCP settings should be adjusted for very high concurrency situations? (i.e. how to avoid such high memory usage). Thanks.

comment Fast small static file serving on a VPS - avoiding the Disk
Quick question - do you know if this starts copying the whole folder into memory as soon as you mount this, or does it load each file into memory the first time it's requested?

comment Fast small static file serving on a VPS - avoiding the Disk
Thanks. I just have a hard time believing that the standard built in hot file caching config will work in all scenarios. I mean, will it really keep 1GB of files cached in memory?

That looks great too thanks. I was wondering how to get some visibility into this under the hood magic.

Well that's pretty close, but its really a badly titled question (it's about a specific error he has, not nginx/ram in general). I'm also open to non nginx approaches.

@mindthemonkey do you know where I could find more information on this? E.g. how to monitor what is in memory, how to adjust config etc.? Thanks

comment Serve up s3 file with nginx
@ErikA - I disagree that using S3 will improve normal performance. Average reposne time for s3 can approach 800ms (you can serve yourself much faster than this). It was not intended as a CDN, rather a storage mechanism (Cloudfront is the CDN offering). Reliability will be better of course, as will relative performance at high scales.

comment Virtual Private Servers/Cloud hosting - Suitable for CPU intensive tasks?
I mean that CPU is going to be the bottleneck. How do you want me to define it?

comment Virtual Private Servers/Cloud hosting - Suitable for CPU intensive tasks?
The hybrid approach sounds interesting - can you give any examples of hosting providers that offer this? I don't know of any...
