From 2e3c76bf9857f5ac2814df9fd6b9b5b7a7eff88a Mon Sep 17 00:00:00 2001 From: Pieter Wuille Date: Fri, 29 Mar 2013 02:48:59 +0100 Subject: [PATCH] Don't use -dbcache for BDB anymore -dbcache was originally used to set the maximum buffer size in the BDB environment, and was later changed to set the chainstate cache and leveldb caches. No need to use it for BDB now that only the wallet remains there. This should reduce memory allocation (but not necessarily memory usage) a bit. --- src/db.cpp | 7 +++---- 1 file changed, 3 insertions(+), 4 deletions(-) diff --git a/src/db.cpp b/src/db.cpp index 94629f3c..e51d5d2c 100644 --- a/src/db.cpp +++ b/src/db.cpp @@ -75,11 +75,10 @@ bool CDBEnv::Open(const boost::filesystem::path& path) if (GetBoolArg("-privdb", true)) nEnvFlags |= DB_PRIVATE; - unsigned int nDbCache = GetArg("-dbcache", 25); dbenv.set_lg_dir(pathLogDir.string().c_str()); - dbenv.set_cachesize(nDbCache / 1024, (nDbCache % 1024)*1048576, 1); - dbenv.set_lg_bsize(1048576); - dbenv.set_lg_max(10485760); + dbenv.set_cachesize(0, 0x100000, 1); // 1 MiB should be enough for just the wallet + dbenv.set_lg_bsize(0x10000); + dbenv.set_lg_max(1048576); dbenv.set_lk_max_locks(40000); dbenv.set_lk_max_objects(40000); dbenv.set_errfile(fopen(pathErrorFile.string().c_str(), "a")); /// debug
