For code like `Observable.from(1)` Improve performance from ~3.9m to 4.5+m ops/second Before; ``` r.u.PerfTransforms.flatMapTransformsUsingFrom 1 thrpt 5 3923845.687 46657.660 ops/s r.u.PerfTransforms.flatMapTransformsUsingFrom 1024 thrpt 5 8924.953 1983.161 ops/s r.u.PerfTransforms.flatMapTransformsUsingFrom 1 thrpt 5 3623228.857 490894.492 ops/s r.u.PerfTransforms.flatMapTransformsUsingFrom 1024 thrpt 5 9176.330 923.929 ops/s ``` After: ``` Benchmark (size) Mode Samples Mean Mean error Units r.u.PerfTransforms.flatMapTransformsUsingFrom 1 thrpt 5 4052364.587 100971.234 ops/s r.u.PerfTransforms.flatMapTransformsUsingFrom 1024 thrpt 5 11682.783 496.656 ops/s Benchmark (size) Mode Samples Mean Mean error Units r.u.PerfTransforms.flatMapTransformsUsingFrom 1 thrpt 5 4700583.987 77742.037 ops/s r.u.PerfTransforms.flatMapTransformsUsingFrom 1024 thrpt 5 12588.803 58.935 ops/s ``` Using this test: ``` ../gradlew benchmarks '-Pjmh=-f 1 -tu s -bm thrpt -wi 5 -i 5 -r 5 -prof GC .*PerfTransforms.flatMapTransformsUsingFrom*' ```
