Arduino circuit not responding - c++

Question

I am trying to control a car/wheeled robot basically with this code. The problem here is that if I send signals faster than 0.9 seconds, the Arduino cannot process it. Is there any way to fix it?
(I have checked the serial monitor from a different computer and it shows the Arduino still receives the signal but it doesn't provide the output to my motor controller).
Any help would be appreciated. Thanks.
#include <Servo.h>
//Using mega 2560 and sabertooth 2x12 dip switch 010111
int onevar;
int twovar;
Servo myservo;
Servo myservo2;
void setup() {
// put your setup code here, to run once:s
pinMode(servo1, OUTPUT);
pinMode(servo2, OUTPUT);
Serial.begin(9600);
myservo.attach(servo1);
myservo2.attach(servo2);
Serial.setTimeout(10);
//works for 10ms 0.9s need to figure out
}
void loop() {
// put your main code here, to run repeatedly:
// Receive up to 7 bytes
if (Serial.available()>0) {
// Wait for characters
onevar = Serial.parseInt();
twovar = Serial.parseInt();
//number = atoi(buffer);
Serial.println(onevar);
Serial.println(twovar);
/* if (Serial.available() > 0) {
number = Serial.read()-'0'; // read the incoming byte:
Serial.print(number);
*/
myservo.write(onevar);
// 93 is stop backward and forward is scalable range 25 to 155
myservo2.write(twovar);
//93 is no steering 30 to 160
}
}

Answer 1

A few things to try:
Serial.begin(9600);
Try setting the baud rate higher (on both ends).
Serial.println(onevar);
Serial.println(twovar);
Comment those out for some testing.
Servo myservo;
Servo myservo2;
2 servos and 1 serial port. It could happen that there is a conflict with the timers (multiple libraries using/setting the same timer). Does it work with 1 servo?
