Hudson commented on THRIFT-959: ------------------------------- Integrated in Thrift #283 (See [https://builds.apache.org/job/Thrift/283/]) revert THRIFT-959 bryanduxbury : http://svn.apache.org/viewvc/?view=rev&rev=1176472 Files : * /thrift/trunk/lib/java/src/org/apache/thrift/transport/TSocket.java > TSocket seems to do its own buffering inefficiently > --------------------------------------------------- > > Key: THRIFT-959 > URL: https://issues.apache.org/jira/browse/THRIFT-959 > Project: Thrift > Issue Type: Improvement > Components: Java - Library > Affects Versions: 0.2, 0.3, 0.4, 0.5 > Reporter: Bryan Duxbury > Assignee: Bryan Duxbury > Fix For: 0.6 > > > I was looking through TSocket today while reviewing THRIFT-106 and I noticed > that in TSocket, when we open the socket/stream, we wrap the input/output > streams with Buffered(Input|Output)Stream objects and use those for reading > and writing. > Two things stand out about this. Firstly, for some reason we're setting the > buffer size specifically to 1KB, which is 1/8 the default. I think that > number should be *at least* 8KB and more likely something like 32KB would be > better. Anyone have any idea why we chose this size? Secondly, though, is the > fact that we probably shouldn't be doing buffering here at all. The general > pattern is to open a TSocket and wrap it in a TFramedTransport, which means > that today, even though we're fully buffering in the framed transport, we're > wastefully buffering again in the TSocket. This means we're wasting time and > memory, and I wouldn't be surprised if this is artificially slowing down > throughput, specifically for multi-KB requests and responses. > If we remove the buffering from TSocket, I think we will probably need to add > a TBufferedTransport to support users who are talking to non-Framed servers > but still need buffering for performance. -- This message is automatically generated by JIRA.
