That is useless, because the thing that actually ruins a VPS is variance &#8212; a box that hits 4000 IOPS and then 90 IOPS five minutes later is worse than one that steadily delivers 1200. This guide gives you a measurement harness that quantifies the variance, so a benchmark tells you about the host&#8217;s behaviour, not about the one happy window it was measured in.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Run it against any <a href=\"https:\/\/virtualserversvps.com\/\">VPS you are evaluating before committing production traffic<\/a>, and re-run it on the same instance at different hours. The same harness applies to the comparison mindset laid out on the <a href=\"https:\/\/virtualserversvps.com\/\">site&#8217;s benchmarking resources<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why single-shot benchmarks lie<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">On a shared host, your vCPUs are time-sliced against other tenants. A single <code>sysbench<\/code> run of 30 seconds may land entirely in a quiet window or entirely in a contention storm. The metric that separates a good host from a bad one is the distribution across many samples, and specifically the tail &#8212; p99 and worst-case, not mean.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Harness 1: Repeated disk latency with percentiles<\/h2>\n\n\n\n<pre class=\"wp-block-code\"><code>fio --name=lat --ioengine=libaio --rw=randread --bs=4k \\\n    --iodepth=1 --direct=1 --runtime=10 --time_based=0 \\\n    --loops=20 --group_reporting \\\n    --percentile_list=50:95:99:99.9 \\\n    --output-format=json &gt; \/tmp\/fio.json\n\njq '.jobs[0].read.clat_ns.percentile' \/tmp\/fio.json<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Queue-depth-1 random reads isolate single-stream latency from queueing effects. On a well-behaved NVMe-backed instance you should see a tight distribution &#8212; p50 and p99 within roughly 2-3x of each other. A p99 that is 20x the p50 means noisy neighbours or a heavily overcommitted storage backend. This is the single most diagnostic test you can run.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Harness 2: Sampling CPU steal over time<\/h2>\n\n\n\n<pre class=\"wp-block-code\"><code>for i in $(seq 1 60); do\n  awk '\/^cpu \/{t=$2+$3+$4+$5+$6+$7+$8; idle=$5; steal=$9; printf \"%s cpu_steal=%.2f%%\\n\", systime(), steal*100\/t}' \/proc\/stat\n  sleep 5\ndone<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Steal time is the percentage of time your vCPU was ready to run but the host scheduled someone else. Under 1% sustained is healthy; spikes above 5% mean the host is oversubscribed. Five minutes of sampling every five seconds across a full hour gives you a picture a one-liner cannot. Correlate spikes with wall-clock time &#8212; if steal climbs every evening, the host shares a physical machine with daytime-fatigued tenants.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Harness 3: Memory bandwidth stability<\/h2>\n\n\n\n<pre class=\"wp-block-code\"><code>for i in $(seq 1 10); do\n  sysbench memory --memory-block-size=1M --memory-total-size=5G --threads=2 run \\\n    | grep -E 'transferred|MiB\/sec'\nddone<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Memory bandwidth on a shared host is affected by NUMA placement and memory ballooning. Consistent numbers across ten runs mean your pages are resident and stable. If bandwidth degrades within a session, the host is reclaiming or migrating your memory &#8212; a strong signal of oversubscription.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Harness 4: Network throughput to multiple endpoints<\/h2>\n\n\n\n<pre class=\"wp-block-code\"><code>for peer in iperf.he.net speedtest.ams1.nl; do\n  for run in 1 2 3; do\n    iperf3 -c \"$peer\" -t 15 -O 3 -P 4 2&gt;\/dev\/null | grep receiver\ndone; done<\/code><\/pre>\n<!-- \/wp:code>\n\n\n<p class=\"wp-block-paragraph\">The port matters as much as the throughput. Explicitly test throughput to endpoints in each region your users live, because a provider claiming \"10 Gbit\" may route beautifully to one datacentre and poorly to another. Record the first-hop latency too -- <code>mtr -rwzc 20 &lt;peer&gt;<\/code> reveals whether the provider's own network or a transit handoff is the bottleneck.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Harness 5: Sustained write endurance<\/h2>\n\n\n\n<pre class=\"wp-block-code\"><code>fio --name=sustained --ioengine=libaio --rw=write --bs=1M \\\n    --iodepth=8 --direct=1 --runtime=300 --time_based \\\n    --filename=\/tmp\/testfile --size=2G\nrm -f \/tmp\/testfile<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Many VPS disks are fast for the first 30 seconds and collapse once their burst credits are consumed. A five-minute sustained write exposes this: watch whether throughput holds steady or decays. A decay to under 30% of the initial rate is burst-credit exhaustion, which will bite you badly during a backup window or a large database write.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Interpreting the results<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Score each dimension on its worst case, not its best. A host with modest but consistent performance is a better production platform than one with spectacular peaks and deep troughs. Tabulate like this:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>Dimension          p50        p99 \/ worst    Verdict\n4k read latency    0.09 ms    0.21 ms        tight -> good\nCPU steal (1h)     0.3%       2.1%           healthy\nmem bw variance    +-4%       -18%           borderline\nsustained write    180 MB\/s   55 MB\/s        burst-limited\nnet to EU          940 Mbit   n\/a            solid<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Team this with long-run monitoring such as Prometheus node-exporter so you have a continuous record, not a snapshot. The benchmark tells you whether to deploy; the monitoring tells you when to leave.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Running the benchmark reproducibly<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Lock the environment before measuring: stop application services, set the performance governor if available, drop filesystem caches with <code>sync; echo 3 &gt; \/proc\/sys\/vm\/drop_caches<\/code> between disk runs, and record the kernel version and hypervisor with <code>uname -r<\/code> and <code>systemd-detect-virt<\/code>. A benchmark is only comparable if the conditions are recorded alongside the numbers. Publish the conditions or the numbers mean nothing.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Provider benchmark posts usually publish a single lucky number and call it a review.
