On: Ask HN: LZ4 was not added as an optional compressor in HTTP/2, why gzip only?

[DiabloD3]

Your phone won't require it. It will temporarily use slightly more memory (12MB is very little on modern Android phones), and it would decrease the time required to render the page (due to less CPU power required to compress then decompress over gzip -1).

Well, it will use much less than that. The real "memory cost" of decompression will be : + compressed size

and that's it. Decompression doesn't use any memory, only the I/O buffers.

On the compression side, the memory cost is : + buffer for compression (typically == size of data to compress) + 16 KB for tables

And that's it.

We are very very far from the 12 MB mentioned.

My concern is with your general concept of:
