GitHub user mdvorsky opened a pull request:

    https://github.com/apache/incubator-beam/pull/752

    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.
