   Describe the issue

   When running two pruned nodes, one for mainnet and one for testnet3, the memory usage of the testnet3 daemon is much higher than the mainnet node.

   Can you reliably reproduce the issue?

   If so, please list the steps to reproduce below:

   Relevant entries in bitcoin.conf:

   0disablewallet=1
   1listen=1
   2rest=1
   

   mainnet

   0prune=6480
   

   testnet3

   0prune=1024
   

   Steps to reproduce:

   run bitcoind -maxmempool=100 -dbcache=16 run bitcoind -testnet -maxmempool=100 -dbcache=16

   Expected behaviour

   I would expect memory usage to be relatively equivalent across the two instances.

   Actual behaviour

   Immediately after start, mainnet has approx. 250M resident whilst testnet has approx 450M resident.

   Both nodes are synced to the latest height (484225 main, 1181354 test).

   What version of bitcoin-core are you using?

   v0.15.0rc3 verified signed binaries from bitcoin.org/bin.

   Machine specs:

   Linode 1024 VPS, Ubuntu 16.04 LTS with 1GB RAM, 20GB SSD.

   Testnet has way more blocks and occasionally way more spam as people test random stuff on testnet. I don’t find this really all that surprising.

   I agree this isn’t really an issue. Testnet is exactly for testing random stuff, spamming, trying to break things. It can also be reset, in which case the resource requirements can change dramatically. Closing this.
