RFC - ws2_32/socket.c: SIO_KEEPALIVE_VALS vs TCP_KEEPIDLE/TCP_KEEPINTVL
by Bruno Jesus 30 Aug '11

30 Aug '11

This discussion is related to the test failing in bug 21271: http://bugs.winehq.org/show_bug.cgi?id=21271 The SIO_KEEPALIVE_VALS message on windows takes parameters as miliseconds, on some other systems there are the equivalent TCP_KEEPIDLE/TCP_KEEPINTVL which takes the parameters as seconds. To solve this there is a division by 1000 on wine source code but the problem is that values < 1000 become 0 making the setsockopt function return error. Is it reasonable to do a check to see if the result of the division is zero and then set the variable to one so we can get closer to the windows implementation and not fail the setsockopt function? It will obviously not match 100% the windows implementation but it seems to be as close as we can get and as far as I can think it's better for the applications to receive a one second keepalive then never receiving any. SIO_KEEPALIVE_VALS bibliography (read specially the remarks): http://msdn.microsoft.com/en-us/library/dd877220%28v=vs.85%29.aspx TCP_KEEPIDLE/TCP_KEEPINTVL bibliography (almost no information, sorry) http://linux.die.net/man/7/tcp http://www.yolinux.com/TUTORIALS/Sockets.html Wine source code link (ignore the fact that there may be a read on address zero that is only checked later): http://source.winehq.org/source/dlls/ws2_32/socket.c#L3362 I have tested locally and will try to add tests to wine git but I prefered to start the discussion first. If I have missed something or this was already discussed accept my apologies in advance. Best wishes, Bruno

I assume you meant "encountering a _wine_ bottleneck" since clearly above your MSYS tests of make.exe and bash.exe on Windows don't have the large startup latencies you encounter with wine-1.2 and wine-git. How does the MSYS version of make (make.exe that you tried above) compare in this regard with the MinGW version of make (MinGW/bin/mingw32-make.exe) that specifically excludes everything to do with MSYS? My guess is you will encounter a similar wine bottleneck for this case as well, but it is worth verifying that. And now you have done a clean comparison with the same software stack it is clear that wine-git somewhat reduces the bottleneck compared to wine-1.2. Thus, I expect my own planned clean comparisons to show the same. So I have changed the subject line appropriately. Now, if someone could just figure out what the wine bottleneck is that is causing these severe start-up latencies for Windows applications.... Alan __________________________ Alan W.

Severe regression in wine startup latencies
by Alan W. Irwin 30 Aug '11

30 Aug '11

The startup latency of commands run under wine-1.3.27 is much worse than it used to be. I did the following experiment with bash-3.1.17 that you get with the latest (mingw-get-inst-20110802.exe) MinGW/MSYS installer. wineconsole --backend=curses MinGW/msys/1.0/bin/bash.exe Then I ran the following commands within that MSYS bash environment. bash.exe-3.1$ which echo /z/home/wine/newstart1/MinGW/msys/1.0/bin/echo.exe bash.exe-3.1$ time echo "hello" hello real 0m0.000s user 0m0.000s sys 0m0.000s This shows there is at least one command (echo) available under wine that executes with essentially zero latency. So the problem cannot be the time wine takes to read the executable file (/z/home/wine/newstart1/MinGW/msys/1.0/bin/echo.exe in this case). But the rest of the commands I tried had latencies near 1 second. (I only report the second run in each case to make sure as much as possible is cached in memory for maximum speed.) bash.exe-3.1$ time bash --version GNU bash, version 3.1.17(1)-release (i686-pc-msys) Copyright (C) 2005 Free Software Foundation, Inc. real 0m0.905s user 0m0.160s sys 0m0.060s bash.exe-3.1$ time cmake-2.8.5-win32-x86/bin/cmake --version cmake version 2.8.5 real 0m0.922s user 0m0.080s sys 0m0.020s bash.exe-3.1$ time make --version GNU Make 3.81 Copyright (C) 2006 Free Software Foundation, Inc.

Although startup latencies are not much of an issue if you are running just one command such as a game, they are a serious issue for those like me attempting to build software on the wine platform. I previously complained here about this issue for cmake-1.3.9 where cmake configuration and make commands were roughly 2-3 times slower than the corresponding Linux case because both commands execute _a lot_ of subcommands where latency delays accumulate like crazy. But now that the wine-1.3.27 latency is 10 times worse than in the 1.3.9 case, typical cmake configurations are something like 25 (!) times slower than the corresponding Linux command. What can be done to address this bad command-startup latency regression for wine? I would be happy to run any tests that might point to a solution. For example, I did run "top" from time to time while running the very long cmake configuration step, and the cpu's (I have a duo core system) were mostly idle indicating the latency bottleneck (whatever it is) does not involve excessive amounts of cpu time. However, wineserver was always high in the "top" list of commands that were grabbing the most cpu. If wine sets up a detailed GUI environment for every command it runs is there an easy way to turn that off in case that is the cause of the startup latency? (All the builds I want to do on the MinGW/MSYS/wine platform are strictly from the MSYS bash command line with no GUI required.) Alan __________________________ Alan W.

buildbot status
by Dan Kegel 29 Aug '11

29 Aug '11

The buildbot now uses ccache, which sped up builds tremendously. Cycle time of build slaves with ccache using is 10-11 minutes; the e8400 and q9300 are almost as fast as the i7 now. (Dunno about the celeron yet.) A few more flaky tests are now blacklisted, and the cluster has been running all afternoon without a glitch. I hope to turn on email notifications sometime this week.
