* ci: add per-process memory sampler for perf jobs
Samples VmRSS once a second into a CSV and records peak VmHWM per process
on stop. Linux only; reads /proc/<pid>/status.
* ci: run perf benchmarks on the Rust volume server and report memory
Matrix the throughput and S3 jobs over go/rust volume servers, using a
standalone master (plus filer for S3) and swapping only the volume binary
so the two are directly comparable. Sample peak RSS in every job and surface
it per impl in the run summary.
* ci: harden mem sampler arg handling and peak fallback
Guard against missing args under set -u, and fall back to the max RSS
sampled when a process exits before VmHWM can be read.
* test: add self-contained S3 read/write load tool
Concurrent PUT/GET against the S3 gateway, reporting requests/sec,
transfer rate, and latency percentiles. Built on the aws-sdk-go-v2
client the S3 tests already use, so no extra benchmark binary is needed.
* ci: add performance workflow
Three parallel jobs: cpu/heap pprof of the server under write load,
native throughput via weed benchmark plus the Go micro-benchmarks, and
an S3 read/write benchmark against the gateway. Runs on push to master
and manual dispatch with tunable duration, object count, size, and
concurrency.
