There are a number of lag fixes around.
I personally am using the original RyanZA lag fix, entered manually on the adb command line.
For anyone else, you have 3x choices.
- RyanZA’s one click lag fix. I would suggest this as its easiest and it delivers resonable performance without any hassel. For this fix – jump into market and search for “lag fix”.
- Voodoo lag fix – apparently the fastest fix – but its very ‘new’ and I haven’t bothered with it yet.
- The external SD card fix – which some people recommend as being really great. Of course you need an External SD & the install process is quite complicated compared to the others.
