For improving IPFS GET performance

Hi, everyone.
I’m studying IPFS.
I found something to share, but it may be my misunderstanding IPFS.

In the source, responseemitter.go( and extractor.go (, there are hard-coded value, 4096.

After changing this value to 256k(in fact, 262144), I tested and found the IPFS GET performance improvement (upto 720MB/s) in small- sized-file(5.5MB) case, but not big-sized-file case.

I guess this value can effect the throughput of download in various context, and must be a member in the configuration.
