2018-02-08Minimize bihash memory consumptionDave Barach1-93/+145
Reference-count the number of entries in each bucket. If the reference count goes to zero, free the backing store. Add long-term churn-testing to test_bihash_template.c, thanks to Andrew Yourtchenko for the initial implementation.

2017-07-19Add a bihash prefetchable bucket-level cacheDave Barach1-6/+55
According to Maciek, the easiest way to leverage the csit "performance trend" job is to actually merge the patch once verified. Manual testing indicates that the patch improves l2 path performance. Other use-cases are TBD. It's possible that we'll need to back out the patch depending on what happens.

2017-05-18VPP-847: improve bihash template memory allocator performanceDave Barach1-1/+44
Particularly in the DCLIB_VEC64=1 case, using vectors vs. raw clib_mem_alloc'ed memory causes abysmal memory allocator performance. Change-Id: I07a4dec0cd69ca357445385e2671cdf23c59b95d Signed-off-by: Dave Barach <dave@barachs.net>
