Sync-perf tuning for bitcoin/bitcoin-core/bitcoin-knots/electrumx. - Drop the --cpus=2 cap on bitcoin/electrumx variants. Script verification is parallelizable; the cap halved IBD speed on 4-8 core machines. - Bump bitcoin --memory 4g→8g so dbcache=4096 has headroom for mempool + connection buffers + I/O. 4g was OOM-prone during heavy IBD. - Bump electrumx --memory 1g→2g + add CACHE_MB=2048 + MAX_SEND=10MB. - bitcoin-core CLI args gain -dbcache=4096 -par=0 -maxconnections=125. - bitcoin-knots manifest matched (1024MB pruned / 4096MB full + par=0). Future v2: host-RAM-aware dbcache scaling. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
