You forgot to attach your m-file so how could we possibly know why it's slow? I don't see any reason at all why adding comments to the code should speed it up. This isn't a compiled program is it?

sorry i could not uderstand your comment.. what i supposed to do, should i upload the code or what?

If I told you MY program was slow, can you tell me why my program is slow if I don't show you the code? You need to see the code. Did you use the MATLAB compiler to turn your program into a standalone executable?

Code

function fgui2_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
% varargin   command line arguments to fgui2 (see VARARGIN)

% Choose default command line output for fgui2
handles.output = hObject;
imgNameList = {'images.jpg','images (1).jpg','images (2).jpg','download.jpg','images (4).jpg','images (5).jpg','images (6).jpg','images (7).jpg','eye3.jpg'};
subplot(2,2,4);
pause on;
for i = 1:length(imgNameList) 
    a = imread(imgNameList{i}); 
    imshow(a); 
    drawnow; 
    pause(3);
end

% Update handles structure
guidata(hObject, handles);

You can use following code to run slideshow because it will run in background.

function slideshow
global indx
indx=1;
showTimer=timer('timerFcn',@timefcn);
set(showTimer,'ExecutionMode','fixedRate');    
start(showTimer)

function timefcn(varargin)
global indx
imgNameList= char('1.jpg','2.jpg','3.jpg');
    a=imread(imgNameList(indx,:)); 
    indx=indx+1;
    if indx>10
        indx=1;
    end
    imshow(a);
    drawnow;

As your code is not present here its difficult to say anything. But,if gui is taking time in launching that means you have written a bunch of code in its opening function that takes time. I am not sure but this may be one of the reason.

Code

function fgui2_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
% varargin   command line arguments to fgui2 (see VARARGIN)

% Choose default command line output for fgui2
handles.output = hObject;
imgNameList = {'images.jpg','images (1).jpg','images (2).jpg','download.jpg','images (4).jpg','images (5).jpg','images (6).jpg','images (7).jpg','eye3.jpg'};
subplot(2,2,4);
pause on;
for i = 1:length(imgNameList) 
    a = imread(imgNameList{i}); 
    imshow(a); 
    drawnow; 
    pause(3);
end

% Update handles structure
guidata(hObject, handles);

You used pause(3) which delays gui to appear.
