how much internal buffer does esp8266 have?

[doughboy]

I know cipsend limit says 2048 bytes, but I am curious if internally, esp8266 provides separate buffers for tx and rx for each of the 5 sockets, hence a total of 20k buffer internally?

The wiz w5100 chip has 16k buffer internally that provides separate 2k for tx and rx for each of 4 sockets.

is esp8266 using only 2048 bytes for both tx and rx for all 5 sockets?

I want to know too.
