[GitHub] incubator-beam pull request #752: Beam Python GCSIO write performance improv...

Beam Python GCSIO write performance improvements.

Increased the GCS buffer size from 1MB to 8MB and introduced a 128kB buffer 
for the pipe. 

Increasing the GCS buffer even more could improve the performance, but for 
the price of spending a lot of memory on buffers (which can be a problem if 
many GCS files are being written to concurrently).

Increasing the pipe buffer further appears to have no benefit.
