They could further reduce their server load if they utilized MemSQL, as well as MemCache based object caching.
It's been benchmarked to 80,000 queries a second.

But TEST it carefully. Sometimes memcache is fast. Sometimes it's slower than even NFS. It really, really depends on the workload.
A semi truck is the fastest way to get a load of lumber across town. A motorcycle is faster to carry a letter. The motorcycle would take a month to carry the lumber though, one piece at a time. Sometimes memcache is the right tool for the job. Often, memcache is exactly the wrong tool for the job.Last edited by raymor; 07-08-2012, 03:13 PM.For historical display only.

Nothing against raymor, he knows his Apache well but didn't we prove noatime was incorrect?

If setup properly, these two things could reduce this forum to a single server, or reduce the amount of servers needed significantly if it is using a cluster now.Last edited by BradBreakfast; 07-08-2012, 03:19 PM.GetClicky - The World's Most Advanced Real Time Ajax-based AnalyticsComment

Well after all my posts, one person knows. I did think about mentioning what Linus calls the number one performance improvement you can make in Linux.
I figured we can assume noatime on any performance system by now because most sysadmins worth the title have heard what kernel developer Ingo Molnar said:
Linus called atime "perhaps the most stupid Unix design idea of all times" and Alan Cox cited performance improvements of 50% to 100%, so I assumed the GFY admins have done that already.Atime updates are by far the biggest IO performance deficiency that Linux has today. Getting rid of atime updates would give us more everyday Linux performance than all the pagecache speedups of the past 10 years, _combined_.
(Though if they switched web servers and left atime on, yeah that would be a real screw up and a waste of time.)Last edited by raymor; 07-08-2012, 03:30 PM.For historical display only. This information is not current:

Relatime is a good choice, which I believe is maintained by Igor Molnar. My servers have always been relatime mounted for the past few years now, so maybe it's already a default on several hosts or certain distros?- Free Premium Domain Lists and Tools at Clickmojo.com

Yes in a highly dynamic environment memcache will not be very effective.But TEST it carefully. Sometimes memcache is fast. Sometimes it's slower than even NFS. It really, really depends on the workload.
A semi truck is the fastest way to get a load of lumber across town. A motorcycle is faster to carry a letter. The motorcycle would take a month to carry the lumber though, one piece at a time.

I believe relatime is in fact the default for several distros and was created by Molnar in this famous thread:
http://kerneltrap.org/node/14148
relatime is a good default when you don't know the workload. If you know that tmpwatch and mail are set up to work without atimes, noatime performs better.For historical display only. This information is not current:
