LZMA vs LOLZ & Scan Compress Method

[yasitha]

Precompressor is really necessary?. why can't i use
SREP+LZMA or LOLZ or LZMA2?

Why do we have to use Precompressor.
It's slowing down extremely,
That's why i ask to get better answer
From tou guys.

I have done more testing...

With oodle compression it took 16h to complete.
Without oodle, it only took 5 hours to complete.
both are use the same srep +lzma options.
Oodle is extremely slow.

Different BTW just one DVD.
With srep+lzma 9xDVD5 final disk 3.98GB
with oodle 8xDVD5 final disk 750mb

For installing oodle take to much time like 1h 35m
And use cpu 100% all the time.

With srep+lzma only use 30% under,
and install around 35m / 45m

so my question is Precompressor is really necessary?
If i don't use that, i can save lot of time.

is there any other trick available,
That i can use with srep+lzma
To get better ratio?
