From 32cab91278651d07a11132b7636dc3d21144e616 Mon Sep 17 00:00:00 2001 From: "Wladimir J. van der Laan" Date: Mon, 27 Jun 2016 15:39:28 +0200 Subject: Bump `-dbcache` default to 300MiB Also cap the allocation for the leveldb-specific cache for the UTXO set to 8MiB. This avoids that the extra cache memory goes to the much less effective leveldb cache instead of our application-level cache. --- src/init.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'src/init.cpp') diff --git a/src/init.cpp b/src/init.cpp index 5d29f14eb..22a6af74e 100644 --- a/src/init.cpp +++ b/src/init.cpp @@ -1216,10 +1216,10 @@ bool AppInit2(boost::thread_group& threadGroup, CScheduler& scheduler) nTotalCache = std::max(nTotalCache, nMinDbCache << 20); // total cache cannot be less than nMinDbCache nTotalCache = std::min(nTotalCache, nMaxDbCache << 20); // total cache cannot be greated than nMaxDbcache int64_t nBlockTreeDBCache = nTotalCache / 8; - if (nBlockTreeDBCache > (1 << 21) && !GetBoolArg("-txindex", DEFAULT_TXINDEX)) - nBlockTreeDBCache = (1 << 21); // block tree db cache shouldn't be larger than 2 MiB + nBlockTreeDBCache = std::min(nBlockTreeDBCache, (GetBoolArg("-txindex", DEFAULT_TXINDEX) ? nMaxBlockDBAndTxIndexCache : nMaxBlockDBCache) << 20); nTotalCache -= nBlockTreeDBCache; int64_t nCoinDBCache = std::min(nTotalCache / 2, (nTotalCache / 4) + (1 << 23)); // use 25%-50% of the remainder for disk cache + nCoinDBCache = std::min(nCoinDBCache, nMaxCoinsDBCache << 20); // cap total coins db cache nTotalCache -= nCoinDBCache; nCoinCacheUsage = nTotalCache; // the rest goes to in-memory cache LogPrintf("Cache configuration:\n"); -- cgit v1.2.3
