Could you tell me how many ram size that the gzip need at least?

[noparkinghere]

I want to migrate the code to a mcu that has only about 20k ram and I test the code in PC .
And found that it need many ram size more that 100k.
I don't know how to lessen the size,when I modify the size of tdefl_compressor,it will lead to many problems like using different gzip method that has a different compressed result or giving a error.

I wanna know how many ram size the gzip need at least?
