Well, here are some comparisons done with my test-prog (attached)
(higher is better):
eterm: ~ 14 000 l/s
xterm: ~ 8 500 l/s
gnome-terminal: ~ 3 500 l/s
frame-buffer: ~ 40 l/s
Btw: I should have written __80__ instead of __50__.
PS: Please note that the attached program is an ad hoc implementation to
do some basic comparisons, and not a sophisticated program. Compile it
with 'g++ -Wall -O3 <filename.cc> -o <executable>'.
#include <ctime>
#include <iostream>
#include <string>
#include <algorithm>
using namespace std;
static string
rStr("AaBbCcEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz(){}[]?*+-/_-:.;, ");
int main(int argc, char **argv)
{
int lines;
if(argc == 1)
lines = 20000;
else if(argc == 2)
{
lines = atoi(argv[1]);
if(lines < 1000)
{
cerr << "Please enter at least '1000' for lines !" << endl;
return 1;
}
}
else
{
cerr << "Usage: tspeed <lines>" << endl;
return 2;
}
time_t t1 = time(NULL);
for(int i=0; i != lines; ++i)
{
cout << rStr << endl;
random_shuffle(rStr.begin(), rStr.end());
}
time_t t2 = time(NULL);
time_t elapsed = t2-t1;
if(elapsed == 0)
{
cerr << "Writing " << lines << " lines to the screen took less than one second." << endl;
cerr << "Please choose a bigger value for lines." << endl;
return 3;
}
double speed = double(lines)/double(elapsed);
cerr << endl;
cerr << "terminal speed: " << speed << " l/s" << endl;
return 0;
}
