Increase productivity by adding new processors?

Is there a site that has performance on dual processor hardware 450 rps

Question: what performance will have this website, if you put 8-procesarea iron?

Cool question. About how about the number of gears on the bike. Allows it go faster — Yes. Will, if You personally to go faster on this bike — who the hell knows. If you plugging in the disk operations, then the point with the number of processors?
I don't think plugging in drives...
database is on another server, there is a saving in the log.
uptime load on 2 CPU = 3 - mathias0 commented on October 8th 19 at 00:31

0), CPUs are much different
1) kernel especially are very much different. Compare the some bulldozer and Sandy Bridge
2) if performance depends only in the computational core and to assume that the computational ability of the kernel here and there equal the growth will be linear. The web server is one of the most easily scalable to large number of cores task
3) if rested in the base — you no the kernel will not help. Although it will be slightly better due to the fact that worker the web application will not delay on those 2 cores there is.
the uptime on 2 CPU = 3
the base is located on another server
I think that in disk operations performance not limited by,
there is still a small log. - mathias0 commented on October 8th 19 at 00:33
3 what?
3 milliseconds? Or 3 days? In any case not enough for of uptime. - mathias0 commented on October 8th 19 at 00:36
0) Uptime, by definition, the number of cores does not. And is not a dimensionless quantity.
You probably still about the level of LA. LA = 3 — it is a normal value.
1) From the database on another machine in no way implies that you're not a Balk.
2) not necessary to think, and know. Machine you have at hand, though banal top and iostat to watch. - Jacinto_Oberbrunn commented on October 8th 19 at 00:39
>3 milliseconds? Or 3 days?
5-7 milliseconds to process the request - Ignacio_Romaguera commented on October 8th 19 at 00:42
5-7 MS to generate the page? O_o If that database is on a remote machine? Probably still have a local cache with a high percentage to hit him. - mathias0 commented on October 8th 19 at 00:45
it's not really WEB site, this is a social game. If you are interested in architecture, you just write an article about it - davonte commented on October 8th 19 at 00:48
Well, then the value of time is understandable. Lag no one likes. And the architecture would be interesting. - mathias0 commented on October 8th 19 at 00:51

The commentators are absolutely right — it all depends on your site. Put some MERALCO consumption of resources, locate the bottleneck and think already what you need. So soon will be clear how to increase the performance, at least approximately.
Again, read the book of John Allspaw "the Art of capacity planning".
