Awk Performance Issues
Hi All,
I'm facing an issue in my awk script.
The script is processing a large text file having the details of a number of persons, each person's details being written from 100 to 250 tags as given below:
100 START|
101klklk|
...
245 opr|
246 55|
250 END|
100 START|
...
245 pp|
246 65|
250 END|
In the code it writes each individual person's info into a temporary file and then process it for customization
We increased the tags from 250 to 450 leaving almost 200 tags blank.
like from 245 tag to 250 where moved to 445 to 450.(tags from 245-444 will not be coming in the file for now)
But after doing this rearrangment awk script has performance issues of almost double the time. So did changing these tags/identifiers degraded performance?

ImagickDraw::pathCurveToQuadraticBezierSmoothRelative - Draws a quadratic Bezier curve
SYNOPSIS
bool ImagickDraw::pathCurveToQuadraticBezierSmoothRelative (float $x, float $y)
DESCRIPTION
Warning
This function is currently not documented; only its argument list is available.
Draws a quadratic Bezier curve (using relative coordinates) from the current point to (x, y). The control point is assumed to be the
reflection of the control point on the previous command relative to the current point. (If there is no previous command or if the previous
command was not a DrawPathCurveToQuadraticBezierAbsolute, DrawPathCurveToQuadraticBezierRelative, DrawPathCurveToQuadraticBezierSmoothAbso-
lut or DrawPathCurveToQuadraticBezierSmoothRelative, assume the control point is coincident with the current point). At the end of the com-
mand, the new current point becomes the final (x, y) coordinate pair used in the polybezier.
This function cannot be used to continue a cubic Bezier curve smoothly. It can only continue from a quadratic curve smoothly.
PARAMETERS
o $x
- ending x coordinate
o $y
- ending y coordinate
RETURN VALUES
No value is returned.
EXAMPLES
Example #1
ImagickDraw::pathCurveToQuadraticBezierSmoothRelative
<?php
$draw = new ImagickDraw();
$draw->setStrokeOpacity(1);
$draw->setStrokeColor("black");
$draw->setFillColor("blue");
$draw->setStrokeWidth(2);
$draw->setFontSize(72);
$draw->pathStart();
$draw->pathMoveToAbsolute(50,250);
// This specifies a quadratic bezier curve with the current position as the start
// point, the control point is the first two params, and the end point is the last two params.
$draw->pathCurveToQuadraticBezierAbsolute(
150,50,
250,250
);
// This specifies a quadratic bezier curve with the current position as the start
// point, the control point is mirrored from the previous curves control point
// and the end point is defined by the x, y values.
$draw->pathCurveToQuadraticBezierSmoothAbsolute(
450,250
);
// This specifies a quadratic bezier curve with the current position as the start
// point, the control point is mirrored from the previous curves control point
// and the end point is defined relative from the current position by the x, y values.
$draw->pathCurveToQuadraticBezierSmoothRelative(
200,-100
);
$draw->pathFinish();
$imagick = new Imagick();
$imagick->newImage(700, 500, $backgroundColor);
$imagick->setImageFormat("png");
$imagick->drawImage($draw);
header("Content-Type: image/png");
echo $imagick->getImageBlob();
