First of all these SLUB+SLAB microbenchmarks use object size 256 bytes, because network stack alloc object of this size for SKBs/sk_buff (due to cache-align as used size is 224 bytes). Checked SLUB: Each slab use 2 pages (8192 bytes) and contain 32 object of size 256 (256*32=8192). The SLUB allocator have a per-CPU slab which speedup fast-reuse, in this case up-to 32 objects. For SLUB the "fastpath reuse" test this behaviour, and it serves as a baseline for optimal 1-object performance (where my bulk API tries to beat that, which is possible even for 1-object due to knowing bulk API cannot be used from IRQ context). SLUB fastpath: 3 measurements reporting cycles(tsc) - SLUB-patched : fastpath reuse: 184 - 177 - 176 cycles(tsc) - SLUB-original: fastpath reuse: 178 - 153 - 156 cycles(tsc) There are some stability concerns as you mention, but it seems pretty consistently that patched version is slower. If you compile with no-PREEMPT you can likely get more stable results (and remove a slight overhead for SLUB fastpath). The microbenchmark also measures the bulk-API, which is AFAIK only used by network stack (and io_uring). I guess you shouldn't focus too much on these bulk measurements. When bulk-API cross this objects per slab threshold, or is unlucky is it use two per-CPU slab, then the measurements can fluctuate a bit. Your numbers for SLUB bulk-API: SLUB-patched - bulk-API - SLUB-patched : bulk_quick_reuse objects=1 : 187 - 90 - 224 cycles(tsc) - SLUB-patched : bulk_quick_reuse objects=2 : 110 - 53 - 133 cycles(tsc) - SLUB-patched : bulk_quick_reuse objects=3 : 88 - 95 - 42 cycles(tsc) - SLUB-patched : bulk_quick_reuse objects=4 : 91 - 85 - 36 cycles(tsc) - SLUB-patched : bulk_quick_reuse objects=8 : 32 - 66 - 32 cycles(tsc) SLUB-original - bulk-API - SLUB-original: bulk_quick_reuse objects=1 : 87 - 87 - 142 cycles(tsc) - SLUB-original: bulk_quick_reuse objects=2 : 52 - 53 - 53 cycles(tsc) - SLUB-original: bulk_quick_reuse objects=3 : 42 - 42 - 91 cycles(tsc) - SLUB-original: bulk_quick_reuse objects=4 : 91 - 37 - 37 cycles(tsc) - SLUB-original: bulk_quick_reuse objects=8 : 31 - 79 - 76 cycles(tsc) Maybe it is just noise or instability in measurements, but it seem that the 1-object case is consistently slower in your patched version. Mail is too long now... I'll take a look at your SLAB results and followup. -- Best regards, Jesper Dangaard Brouer MSc.CS, Principal Kernel Engineer at Red Hat LinkedIn: http://www.linkedin.com/in/brouer > -- > > SLUB: > > Patched: > [ 444.395174] time_bench: Type:for_loop Per elem: 2 cycles(tsc) 0.773 ns (step:0) -
