From 513a658c87b5fa23533a6b6db36e6d36af6a861d Mon Sep 17 00:00:00 2001 From: moneromooo-monero Date: Thu, 28 Apr 2016 20:25:33 +0100 Subject: add a --max-concurrency flag It sets the max number of threads to use for a parallel job. This is different that the number of total threads, since monero binaries typically start a lot of them. --- src/blockchain_db/berkeleydb/db_bdb.cpp | 2 +- src/common/util.cpp | 23 +++++++++++++++++++++++ src/common/util.h | 3 +++ src/cryptonote_core/blockchain.cpp | 6 +++--- src/daemon/command_line_args.h | 5 +++++ src/daemon/main.cpp | 4 ++++ src/simplewallet/simplewallet.cpp | 7 ++++++- src/wallet/wallet2.cpp | 4 ++-- 8 files changed, 47 insertions(+), 7 deletions(-) diff --git a/src/blockchain_db/berkeleydb/db_bdb.cpp b/src/blockchain_db/berkeleydb/db_bdb.cpp index a7fa556bd..b11570e37 100644 --- a/src/blockchain_db/berkeleydb/db_bdb.cpp +++ b/src/blockchain_db/berkeleydb/db_bdb.cpp @@ -135,7 +135,7 @@ const unsigned int DB_BUFFER_LENGTH = 32 * MB;
