MarcoFalke	5029e94f85	Merge #14519: tests: add utility to easily profile node performance with perf ... 13782b8ba8 docs: add perf section to developer docs (James O'Beirne) 58180b5fd4 tests: add utility to easily profile node performance with perf (James O'Beirne) Pull request description: Adds a context manager to easily (and selectively) profile node performance during functional test execution using `perf`. While writing some tests, I encountered some odd bitcoind slowness. I wrote up a utility (`TestNode.profile_with_perf`) that generates performance diagnostics for a node by running `perf` during the execution of a particular region of test code. `perf` usage is detailed in the excellent (and sadly unmerged) https://github.com/bitcoin/bitcoin/pull/12649; all due props to @eklitzke. ### Example ```python with node.profile_with_perf("large-msgs"): for i in range(200): node.p2p.send_message(some_large_msg) node.p2p.sync_with_ping() ``` This generates a perf data file in the test node's datadir (`/tmp/testtxmpod0y/node0/node-0-TestName-large-msgs.perf.data`). Running `perf report` generates nice output about where the node spent most of its time while running that part of the test: ```bash $ perf report -i /tmp/testtxmpod0y/node0/node-0-TestName-large-msgs.perf.data --stdio \ | c++filt \ | less # To display the perf.data header info, please use --header/--header-only options. # # # Total Lost Samples: 0 # # Samples: 135 of event 'cycles:pp' # Event count (approx.): 1458205679493582 # # Children Self Command Shared Object Symbol # ........ ........ ............... ................... ........................................................................................................................................................................................................................................................................ # 70.14% 0.00% bitcoin-net bitcoind [.] CNode::ReceiveMsgBytes(char const*, unsigned int, bool&) | ---CNode::ReceiveMsgBytes(char const*, unsigned int, bool&) 70.14% 0.00% bitcoin-net bitcoind [.] CNetMessage::readData(char const*, unsigned int) | ---CNetMessage::readData(char const*, unsigned int) CNode::ReceiveMsgBytes(char const*, unsigned int, bool&) 35.52% 0.00% bitcoin-net bitcoind [.] std::vector<char, zero_after_free_allocator<char> >::_M_fill_insert(__gnu_cxx::__normal_iterator<char*, std::vector<char, zero_after_free_allocator<char> > >, unsigned long, char const&) | ---std::vector<char, zero_after_free_allocator<char> >::_M_fill_insert(__gnu_cxx::__normal_iterator<char*, std::vector<char, zero_after_free_allocator<char> > >, unsigned long, char const&) CNetMessage::readData(char const*, unsigned int) CNode::ReceiveMsgBytes(char const*, unsigned int, bool&) ... ``` Tree-SHA512: 9ac4ceaa88818d5eca00994e8e3c8ad42ae019550d6583972a0a4f7b0c4f61032e3d0c476b4ae58756bc5eb8f8015a19a7fc26c095bd588f31d49a37ed0c6b3e	6 years ago

James O'Beirne	58180b5fd4	tests: add utility to easily profile node performance with perf ... Introduces `TestNode.profile_with_perf()` context manager which samples node execution to produce profiling data. Also introduces a test framework flag, `--perf`, which will run perf on all nodes for the duration of a given test.	6 years ago
