Hello Alexey Serbin,
I'd like you to do a code review. Please visit
http://gerrit.cloudera.org:8080/16249
to review the following change.
Change subject: rpc: Change InboundCall arena to 4kB by default
......................................................................
rpc: Change InboundCall arena to 4kB by default
This changes the initial block size of the protobuf::Arena used by
InboundCall to 4kb instead of the 256 byte default. This reduces the
number of allocations required per call significantly for larger
requests/responses.
Benchmarked with:
$ KUDU_ALLOW_SLOW_TESTS=1 ./build/latest/bin/table_locations-itest \
--gtest_filter=TableLocationsTest.GetTableLocationsBenchmark \
--rpc_num_service_threads=32 \
--benchmark_num_threads=48
Before: 59408 req/sec
After: 74787 req/sec (1.25x)
