Brian Brazil	c7e7fd355e	Only send WAL read workers the samples they need. Calculating the modulus in each worker was a hotspot, and meant that you had more work to do the more cores you had. This cuts CPU usage (on my 8 core, 4 real core machine) by 33%, and walltime by 3% Signed-off-by: Brian Brazil <brian.brazil@robustperception.io>	6 years ago
Brian Brazil	a64b0d51c4	Precalculate memSeries.head This is read far more than it changes. This cuts ~14% off walltme and ~27% off CPU for WAL reading. Signed-off-by: Brian Brazil <brian.brazil@robustperception.io>	6 years ago
Brian Brazil	d8c8e4e6e4	Keep local cache of ids. With the various goroutines running, the locking in getByID is notable. This cuts cpu usage by ~25% and walltime by ~20%. Signed-off-by: Brian Brazil <brian.brazil@robustperception.io>	6 years ago

Callum Styan	a971f52ac8	clean up after running repair tests (#372 ) implement a `CopyDirs` helper to walk all dirs and subdirs and copy all files within to a destination folder. Refactor `TestRepairBadIndexVersion` to use the `CopyDirs` so it works on a copy db and remove the copy after the test. This allows running the test more than once and doesn't confuse git.
