Martin Holst Swende	3010f9fc75	eth/downloader: change intial download size (#21366) ... This changes how the downloader works, a little bit. Previously, when block sync started, we immediately started filling up to 8192 blocks. Usually this is fine, blocks are small in the early numbers. The threshold then is lowered as we measure the size of the blocks that are filled. However, if the node is shut down and restarts syncing while we're in a heavy segment, that might be bad. This PR introduces a more conservative initial threshold of 2K blocks instead.	2020-09-02 11:01:46 +02:00

Felix Lange	0bcff8f525	eth/downloader: speed up tests by generating chain only once (#17916) ... * core: speed up GenerateChain Use a mock implementation of ChainReader instead of creating and destroying a BlockChain object for each generated block. * eth/downloader: speed up tests by generating chain only once This change reworks the downloader tests so they share a common test blockchain instead of generating a chain in every test. The tests are roughly twice as fast now.	2018-11-07 15:07:43 +01:00
