This project was written in Go and is intended to aid in comparing the preformance of epoll, select and a traditional multi-threaded network archetecture using go routines. This repository contains the default select scalable server. The other two repositories in this collection can be found here:
I have also written a client that works with all three servers. Full design documents, and a report based off findings from this experiment can be found there as well.
##Usage This server can be envoked using the syntax of:
./COMP8005.SelectScalableServer [Port]When terminated, the process will exit and generate an XLSX report listing clients that had connected, the ammount of data that they transfered and the number of times they transfered data to the server as well as other useful information about the connections.
##Testing This program has been tested to work on Fedora 22 and Manjaro 15 using a modified Go 1.5 compiler. It has been able to sustain over 40k concurrent connections.
In order to monitor over 1024 file descriptors using select in Go, the compiler must be modified, in syscall/ztypes_[os]_[arch].go:
type FdSet struct {
Bits [16]int64
}must be altered. In this case I modified it to:
type FdSet struct {
Bits [2048]int64
}Likely this will not pass the API test when compiled (rightly so, as the Go API specifies that FdSet is 1024bits), and tests will also have to be modified.
