Hi Max, I have done some development on Linux but I’m currently the Wireshark stuff on Windows and Visual Studio. If I get stuck and can’t get the info I need I may put the code on my Centos laptop.
Thanks and regards…Paul From: wireshark-dev-boun...@wireshark.org [mailto:wireshark-dev-boun...@wireshark.org] On Behalf Of Max Dmitrichenko Sent: 21 September 2016 18:19 To: Developer support list for Wireshark <wireshark-dev@wireshark.org> Subject: Re: [Wireshark-dev] The cost of memory allocation 2016-09-21 12:14 GMT+03:00 Paul Offord <paul.off...@advance7.com<mailto:paul.off...@advance7.com>>: Thanks Graham – that’s a great point and I’ll take a look this evening with a Release build. Paul, if you are familiar with Linux, I may recommend you to use callgrind tool from the valgrind toolset for this purpose. Its reports can be viewed with KCachegrind and they are very informative. The only disadvantage is that is slows down execution by the factor of 8-10 since it virtualizes execution of all process'es instructions to estimate accurate number of machine cycles needed for execution and to build a good callgraph. The advantage is that report is not a statistic based on many snapshots of process state but is an accurate estimation of virtually any single function call with a perfect estimation of time taken by the function body and of time taken by all its callees. Also you can use it on a release build without any modification. -- With best regards Max Dmitrichenko ______________________________________________________________________ This message contains confidential information and is intended only for the individual named.
