2018-07-20Fine-grained add / delete lockingDave Barach1-2/+0
Add a bucket-level lock bit. Use a spinlock only when actually allocating, freeing, or splitting a bucket. Should improve multi-thread add/del performance. Change-Id: I3e40e2a8371685457f340d6584dea14e3207f2b0 Signed-off-by: Dave Barach <dave@barachs.net>
2018-06-13Disable bihash bucket-level cachingDave Barach1-1/+1
It'll be interesting to see what the perf trend job says about this change. Change-Id: I66307a19a865011ac9660108098874fa1481c895 Signed-off-by: Dave Barach <dave@barachs.net>

2017-07-19Add a bihash prefetchable bucket-level cacheDave Barach1-0/+3
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.

2017-06-12Remove calls to crc_u32 and add clib_crc32c for armv8+crcChristophe Fontaine1-26/+4
crc_u32 was not defined for non x86_64 with SSE4.2 processors. Calls to "crc_u32" are removed and replaced by either a call to clib_crc32c or a call to clib_xxhash, as the result is not used as a check value but as a hash.
