[jira] [Commented] (THRIFT-1891) Add Windows ALPC transport which
is right counterpart of Unix domain sockets
[ https://issues.apache.org/jira/browse/THRIFT-1891?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13752881#comment-13752881 ]
Ben Craig commented on THRIFT-1891:
-----------------------------------
These are interesting numbers, but the C# results don't seem to be on github anymore.
Was this comparing ncan_np (named pipes) to ncalrpc (LPC?)

> Key: THRIFT-1891
> URL: https://issues.apache.org/jira/browse/THRIFT-1891
> Project: Thrift

> Components: C++ - Library
> Reporter: Dzmitry.Lahoda
> Labels: performance, transport, windows
> Original Estimate: 192h
> Remaining Estimate: 192h

> Reading about local IPC on Windows leads me to idea that Named Pipes is not the transport should be used where Unix Domain sockets are on Unix. Other, most probably faster, should be.
> ALPC and Unix Domain sockets are similar:
> 1. No networking
> 2. Simple names (no specific prefix)
> 3. Articles impress that Windows ALPC and Unix Domain Sockets use more OS "kernel" then Windows Named Pipes.
> Unix Domain sockets and Windows Named Pipes:
> 1. Named pipes are design for Windows Domain printer and file sharing, not local IPC.
> 2. means Named Pipes do some networking even if are local by security.
> True MS design:
> Local Out of process COM and MS-RPC uses ALPC for local inter process communication everywhere in the OS components.
> Can find in many processes via Sysinternals Process Monitor, look for
> ALPC Port : \RPC Control\OLE[RANDOM_GUID].
> Value:
> I think would be faster with lower resource usage.
