When updateing a nightly build on CY 7 does it erase all apps and data

Not unless you choose to wipe Data. You can, and maybe should, clear Cache and Dalvik Cache though. This won't affect your apps/data etc.
don't need wipe,direct install is ok

dalvik cache is a program cache area for the program dalvik. Dalvik is a java based virtual machine that is the bases for running your programs (the ones that have the .apk extension). In order to make access times faster (because there's not JIT (just in time) compiler installed by default), the dalvik-cache is the result of dalvik doing a optimization of the running program. Sounds confusing. It's similar to the prefetch files in Windows. -Andrizoid
And just FYI, you wipe the dalvik cache by booting into Clockworkmod and going to the advanced menu.

Hello all. I just recently got my s2 and have been flashing several Rome. BTW thanks to all the devs and their hard work. Anyways, some of the roms state to do a full wipe. I have been going into recovery and doing wipe cache and data. Is this what is meant by full wipe? Thanks in advance.

Includes what you mention plus dalvik, and everything else except sdcard.

FULL WIPE means you use the wipe data/factory reset.
Wipe cache is seperate BUT INCLUDED when you perform a full wipe. . I think it is just your temporary cache and can be used to help clear out issues on occasions. It wipes the temporary data for the apps but not the dalvich cache of the apps. (I may be slightly off here with that one).
Wipe dalvich cache is seperate and wipes the applications data. It wipes just temporary data that apps are using. This is normally used when you are flashing updates to the rom your on, flashing modems, flashing kernels, etc.
SO when you perform a FULL WIPE it will delete out ALL THE USER APPS AND DATA ASSOCIATED WITH THEM. This is why you backup your USER APPS and their associated data with titanium backup. Once the FULL WIPE is done all user apps are gone and ONLY apps that are included in the rom under system/apps will still be there. All the apps in data/apps are wiped gone. A FULL WIPE does not delete your sdcard so you will not lose your music, pictures, etc.

OK thanks for the insight guys. So is it possible to perform a full wipe from within cwm? Or is it something different entirely?

You wipe from cwm. Wipe data/factory reset and wipe cache partition are on the main cwm screen, wipe dalvik cache is in the advanced menu. Wiping all three of those is considered a full wipe.

You can also do a factory reset from the dial pad: *#*#7780#*#*
I think it's the same as wipe data/factory reset from recovery, but I don't know of any verification of that.
Incidentally, wipe data/factory reset belongs to stock 3e recovery, as well as CWM recovery.
I recently flashed aokp carbon rom on my galaxy sl.
But the performance is weak. Is there any general settings for all aokp rom which will increase performance ? In the rom control option i go to scrolling cache if i need best scrolling what should i set it to
Force enable
Default enable
Default disable
or Force disable ?
thank you guys sorry i am noob
Default enable should do. If that still doesn't improve scrolling, try force enable. Just try the options for yourself and see, that's the best way. You need to give more details about your issue. Elaborate on the 'weak' performance. Also, did you wipe cache & dalvik cache before installing the ROM?

No i was on cm9 before so i did not wipe anything. i directly installled. should i wipe dalvik cache and cache , factory reset ?
now i am on aokp so can i reinstall it again after wiping cche and dalvik cache ? will it mprove the perfomace ?
Change the kernel
sorry but there is only one kernel for ics any other suggestion ?
Yes. You should always wipe dalvik cache and cache when installing a new ROM. Even if it's just a version update of an already installed ROM. It's always better to wipe to avoid usual FC problems. Dalvik cache mainly. The only thing is that your phone will take around 5-6 minutes to boot the first time after you wipe dalvik cache, because it's rebuilding the cache. After that it'll boot normally every other time until you wipe dalvik cache again.
CM9 and AOKP are two different ROMs so when changing between them you should do a full wipe i.e. wipe everything (system, data, cache, dalvik cache and .android_secure folder on the SD card). Otherwise you'll get a lot of FCs. If you do a full wipe all your apps will be gone so you might want to take a Titanium Backup of them or just set them up again when they re-download automatically on the new ROM. Make sure to not restore data of any system apps using Titanium Backup in the new ROM. Once you install the AOKP ROM, upgrading to a newer version won't need a full wipe but only dalvik cache and cache wipe.
About the kernel, just use the one that came with your ROM.

wiping cache/dalvik are a must when flashing any new kernels
What will happen if I boot into recovery and wipe just the system cache without doing a full format of the phone?
I'm looking at trying to sort out some lagging probs I been having the past week. Already cleared all the application caches but still getting noticeable slow downs.

Apps cache will be wipe that's all. Wipe dalviks as well if you want to try removing the lags.

As said by parent, it only formats the cache, so the first boot will be somewhat longer while regenerating it

I would wipe cache wipe dalvik and fix permissions as a matter of course .
Preference when sorting battery drain/lag etc is from a base rom without multiple apps added .

Using flawless ics rom, and i started getting random reboots. Idk why, i didnt use titanium backup at all.
My apps are all useful right now so i dont wanna lose them. So how can i do like some soft wipe that doesnt delete all my apps? I dont want to do backups. Becoz it can lead to random reboot if i restore them.
Did wipe cache but no help.

Wipe Dalvik cache ...thats soft wipe...
Random reboots looks like more of kernel issue ...
The only things you can wipe without loosing data are cache and dalvik cache. But wiping dalvik cache won't change anything, because as far as I know the dalvik cache will be rebuilt on every boot
So try wiping cache or change the kernel for the rom

Dalvik cache is rebuilt only on first boot or if an app is changed via recovery or if you upgrade to higher OS (like ics to JB)...
Some times it gets corrupted and wiping helps...(like 1 in 10 times...) and the cache gets rebuilt (android is upgrading....)
Cache is wiped whenever you reboot so it's one of the most pointless thing to do in recovery for stock roms..(wiping batteystats is the most pointless thing...)
On CM roms ,system dalvik lies in /cache so wiping cache is equivalent to wiping dalvik for system apps..
@OP
Use titanium backup to backup all apps and do a complete wipe..
