I also posted this for others to test on a Q&A section for Galaxy Tab YouTube Lab thread, and while a lot of people had the same problem and had the lag and stutter problem, it was very weird that some people did not have any issue. So I'm curious what you will say.

Its hit or miss with me...most of the time things are fine but sometimes I have a stutter or two. It has been reported on other stock ICS ROM threads that this was a miss on Samsung's part, we can only do so much to help the problem. There are tweaks in Infamous 2.2 as I mentioned, but they most likely won't compensate for a larger issue.
I have been making ROMs & kernel for the Galaxy S phone for quite some time. I have also worked on porting this (CM10.1-based) ROM to the Galaxy tab. I do think, however, that CM10.1 is not worth it (for me!), stock ICS is faster/smoother. And I like the floating apps in the status bar.
I have started to port my kernel to the Galaxy Tab.
-Based on Samsung ICS update 2 sources
-Enable USB charging
-XZ compression of kernel
-BFQv5 scheduler (with upstream improvements)
-ROW scheduler (tweaked, default scheduler)
-many improvements to IO schedulers in general
-GPU overclock (based on A1 kernel)
-1200-1400-1600MHz OC steps (based on A1 kernel)
-150MHz underclock (based on A1 kernel)
-Voltage adjustment (based on A1 kernel)
-Improve the performance of memcpy and memmove
-Kill task closest in size to memory needed to free
-LOAD_FREQ (4*HZ+61) avoids loadavg Moire
-Entropy tweaks: http://lwn.net/Articles/489734/
-arm/crypto: Add optimized AES and SHA1 routines
-build WWAN, NLS & NTFS modules
-CIFS included in kernel
-Removed MMC_CAP_ERASE (so safe for wiping)
You can only flash this if:
-You have a Galaxy Tab 10.1 wifi (also know as GT-P7510 or p4wifi)
-You run a ICS stock rom (so not an AOSP/AOKP/CM-based ROM) - an stock-based ROM such as Infamous is also fine!
I have no plans to port this to other ROMs/devices, as I want to test everything myself and I only own an P7510 running Infamous v2.2. Feel free to port yourself, source can be found through the link given above.
>And all the people who helped me on my i9000 development!
Cool , so you have started supporting another of my devices eh. But I have the P7500 3G model , any chance you will make a version for that ?
Also how do you control GPU OC, which app do we need.
Google Nexus 5 D821
Android version: 4.4.4 KTU48P
Kernel version: 3.4.0 ElementalX 1.0.0
Internals: 2GB RAM, 300-2265MHz CPU with ondemand, ROW
ROM: Stock + Root + Xposed Samsung Galaxy S GT-i9000
Android version: 4.4.2 KVT49L
Kernel version: 3.0.101 CM kernel
Internals: 371MB RAM, 800-1000MHz CPU with ondemand, ROW
ROM: CyanogenMod 11 M7
So the base is A1 Kernel. And AAccount oc'ed his kernel up to 400MHz. It hink its the same in this kernel. Stock is 333 or 300MHz. You can check it yourself, but i dont know the folders to look for right now.
