ofMesh slow fps v0.9.0

thanks for the sample code.
it actually looks like the offending call is ofGetElapsedTimef();

if you move it out of the inner loop and cache the value for the frame above I get 600fps on 0.9.0 and about 500fps on 0.8.4 ( with vertical sync disabled ).

  #include "ofApp.h"


ofMesh mesh;
ofVec3f coords;
ofColor color;
float timeF, noise, alpha;
int size;

//--------------------------------------------------------------
void ofApp::setup(){
    ofSetVerticalSync(false);
    ofSetBackgroundColor(0);
    mesh.setMode(OF_PRIMITIVE_LINE_LOOP);
    alpha = 0.05;
}

//--------------------------------------------------------------
void ofApp::update(){

}

//--------------------------------------------------------------
void ofApp::draw(){
    mesh.clear();
    mesh.clearColors();

    timeF = ofGetElapsedTimef();
    for (float u = 0.0; u < 2 * PI; u += PI / 75) {
        for (float v = 0.0; v < 2 * PI; v += 2 * PI / 75) {


            noise = cos(v) + ofNoise(timeF) * 5.0f;
            size = 100;
            coords.x = sin(v) * size;
            coords.y = cos(u) * size;
            coords.z = sin(u + timeF) * cos(noise) * size;
            color = ofFloatColor(.85,0.9,0.90, u * alpha);


            //Create
            mesh.addColor(color);
            ofVec3f vec = ofVec3f(coords);
            mesh.addVertex(vec);
        }
    }

    float r = ofGetElapsedTimef() * 5.0;
    ofPushStyle();
    ofPushMatrix();
    ofTranslate(ofGetWidth() * .5, ofGetHeight() * .5);
    ofRotateX(r);
    ofRotateY(r);
    ofRotateZ(r);
    mesh.draw();
    ofPopMatrix();
    ofPopStyle();

    ofDrawBitmapString("FPS: " + ofToString(ofGetFrameRate()), ofGetWidth() * .10, ofGetHeight() * .10);
    
}

I'll file an issue for the ofGetElapsedTimef slow down.
Let me know if that fixes it for you.

All the best!
