(*** This bug was imported into bugs.kde.org ***)

Package:           konsole
Version:           1.0.2 (using KDE 2.2.1 )
Severity:          normal
Installed from:    Mandrake Linux Vitamin
Compiler:          gcc version 2.96 20000731 (Mandrake Linux 8.1 2.96-0.62mdk)
OS:                Linux (i586) release 2.4.8-26mdk
OS/Compiler notes: 


Konsole is slow on high volume output. The following is the test program and the test results:

#include <stdio.h>

int main( void )
{
        int x = 600;

        while ( x-- )
                printf( "^^^^^^^^^^^^^^^^^^^^^xxxxxxxxxxxxxxxxxxxxxxxxxxxxx*********************************************************************************99999999999999999999999999999999999999999999999999555555555555555555555555555555555555555555555555555\n" );

        return 0;
}

The time results using the time utility:

Seems that the new refresh algorithmus boosted Konsole by some factors.
