2017-02-07bench: Fix initialization order in registrationWladimir J. van der Laan
The initialization order of global data structures in different implementation units is undefined. Making use of this is essentially gambling on what the linker does, the so-called [Static initialization order fiasco](https://isocpp.org/wiki/faq/ctors#static-init-order). In this case it apparently worked on Linux but failed on OpenBSD and FreeBSD. To create it on first use, make the registration structure local to a function. Fixes #8910.

Fee estimation can just check its own mapMemPoolTxs to determine the same information. Note that now fee estimation for block processing must happen before those transactions are removed, but this shoudl be a speedup.

Make sure that the count is a zero modulo the new mask before scaling, otherwise the next time until a measure triggers will take only 1/2 as long as accounted for. This caused the 'min time' to be potentially off by as much as 100%.

2016-10-27bench: Add benchmark for lockedpool allocation/deallocationWladimir J. van der Laan
2016-10-18Add microbenchmarks to profile more code paths.Russell Yanofsky
The new benchmarks exercise script validation, CCoinsDBView caching, mempool eviction, and wallet coin selection code. All of the benchmarks added here are extremely simple and don't necessarily mirror common real world conditions or interesting performance edge cases. Details about how specific benchmarks can be improved are noted in comments. Github-Issue: #7883
2016-05-31Merge #8115: Avoid integer division in the benchmark inner-most loop.Wladimir J. van der Laan
63ff57d Avoid integer division in the benchmark inner-most loop. (Gregory Maxwell)
2016-05-30Avoid integer division in the benchmark inner-most loop.Gregory Maxwell
Previously the benchmark code used an integer division (%) with a non-constant in the inner-loop. This is quite slow on many processors, especially ones like ARM that lack a hardware divide. Even on fairly recent x86_64 like haswell an integer division can take something like 100 cycles-- making it comparable to the runtime of siphash. This change avoids the division by using bitmasking instead. This was especially easy since the count was only increased by doubling. This change also restarts the timing when the execution time was very low this avoids mintimes of zero in cases where one execution ends up below the timer resolution. It also reduces the impact of the overhead on the final result. The formatting of the prints is changed to not use scientific notation make it more machine readable (in particular, gnuplot croaks on the non-fixedpoint, and it doesn't sort correctly). This also hoists out all the floating point divisions out of the semi-hot path because it was easy to do so. It might be prudent to break out the critical test into a macro just to guarantee that it gets inlined. It might also make sense to just save out the intermediate counts and times and get the floating point completely out of the timing loop (because e.g. on hardware without a fast hardware FPU like some ARM it will still be slow enough to distort the results). I haven't done either of these in this commit.
