Is there any way to speed up the performance?

I'm sorry if anyone before has asked the same things.
I just wonder if there is any way to speed up the performance of renpy.
Example when it does the skip function, the speed is really slow, when there's a transition/ side image exist between dialogue. (like hide XXX with dissolve, etc before the next dialogue). I use so many transition effects so the skip speed is really slow..

Other: I used the readback.rpy and it takes a while before the readback is shown.
The quicksave menu works pretty slow too (maybe because I add too many customized functions on it)

I like renpy's feature, and so many customization that I can do with it, but I hope there's a way to speed up the performance.
I'm using a pretty low spec of laptop, but as far, there's no performance's speed down when I played kiri2 games/ nscripter games.

My laptop processor is Intel Atom N280 1.66 GHz, while my desktop, which has a better performance is Intel Pentium 4 2.8GHz.
Both OS are Win XP.

The performance is better in desktop, but still, the skip's speed is slower than game made by kiri2/nscripter.
I'm not saying that kiri2/nscript is better, since I tried those two before but renpy is easier to understand for me.

I'm sorry for my bad english >< hope anyone here can help me to solve this issue...

*My game's demo is only available in Japanese now, but you can try it to know how "slow" the speed I meant....

Same here!
Dissolve looks horrible on my old notebook and things get even worse when I use screen language (it sometimes takes almost 2 seconds just to switch tabs on interface, mouseover effects are super slow etc).

*glad that there is other member that has same issue...

yeah and when i tried to run my game on android, it's like freezing for 2-3 seconds (or more) before open the readback menu, or when trying to go back to the normal game.
Moreover, after I played it on Android for an hour, the normal text will freeze for 2 seconds (or more) before displayed the next text.

What resolution are you using ? I don't have such slowness issues and I made some games (see my recent Undead Lily test) that has some BIG sprites and pushes Ren'Py to the limits

Well I havent really announced it yet but I'm working on making a ren'py clone in the GO language. However you can expect it wont be done anytime this year.

I'll try to download your game, and if I experienced the slowness within this game too, I'm sure that it is effected by the processor's speed. actually my laptop is not too old (about 1-2 years old) but it is cheap with a not too high spec.
*Add:
I played your game and it looks fine when move right/left, but when I pressed attack, I only saw lily's face zoomed then for next 3-5minutes(not seconds) i can't do nothing beside open the game menu by right-clicking. Then aquaria? comes on the screen, then again the screen only views both of them for 3-5 minutes(and i can't do nothing beside open the game menu) before back to the normal screen.

somehow I felt this is a bit different with the slowness I experienced within my game...
just my feeling though

Maybe you don't have GL driver installed, and you're using software renderer. Can you resize your game window? if not, means you're using software renderer, and I think PyTom might be interested in seeing your opengl.txt file

resize the game window using what? the laptop's graphic property or?
and i saw the open gl logo inside my laptop graphic's property... (sorry i don't know much about the open gl)
and where can i find the opengl.txt?

but the one that i want to know is... is there any way to make renpy game works smoother/ has better performance speed in low spec computer like mine? since i saw kiri2 and nscripter can do it.
and i believe there are lot of people that still using old/low spec pc...

and this is not only about the pc i use, since i also met the worse issue/speed when using my android (xperia x10i)

Resize the window using mouse

you know when you hover in the window angles, you usually can resize windows.
I don't know about android, but I have a netbook similar to your specs and I can run the demo of Undead Lily which is VERY graphic intensive (1280x400px background+ two 1024x300 layers + 8 different "props" + 2 big 1024x1024 sprites all transparent which means lot of VRAM).

Ah I see you played the demo too. Forget about the attack since is broken

but if that one runs smooth, means you're doing something weird in your game, since if that game runs smooth, ANY other visual novel will

Unless you are using 4096x4096 pixel sprites or something weird

I also notice performance lags, but I figured it was because I was making too complicated a game ... testing Ren'Py's boundaries and whatnot. It's funny to have to have a high-end computer for a simple text-sprite game. =P I only started noticing these performance issues when OpenGL came around.

@jack
yeah i know... my code is very ugly ><;;; and now i wonder if there's a way to speed up it since it takes 3-4 seconds to open the readback/backlog in my computer.

and then about the slowness of the skip function... i realized that when there's no side image viewed, the skip speed is normal, like the skip speed when i played the tutorial. but when i used the side image, the speed becomes slow.
i'm using conditional portrait for my side image... and now i'm using around 66 kind of side images... (maybe i use too much?)
but still in some menu, i found so many lag.
