i write an php R web app on a linux server that takes an user input matrix (20X20) and makes an Multidimensional Scaling calculation. Now my answer is, can R support (let's say) 1000 requests per second? (my app is intended to be use on facebook) What's the best way, use R as a server, deployng more than one server with R? i must say that i'ts the first time that i use R on an app. thanks mihai -- View this message in context: http://r.789695.n4.nabble.com/using-R-on-an-php-webapp-tp3208868p3208868.html Sent from the R help mailing list archive at Nabble.com.
