Mal eine Frage an alle VPS200 BF Besitzer: Wie ist denn bei euch die IO Performance? Ich habe ja einige VPS Produkte im Einsatz (mehrere VPS200, VPS500, VPS1000,...) und bei diesen stimmt soweit alles und sie liefern auch super Performance, aber dieser eine VPS200 aus der Black Friday Aktion bereitet mir Kopfzerbrechen.
Reichen Dir die Ausgaben von der älteren, in Debian enthaltenen, Sysbench-Version?
Normaler VPS 200 G8:
# sysbench --test=fileio --file-test-mode=rndrw run
sysbench 0.4.12: multi-threaded system evaluation benchmark
Running the test with following options:
Number of threads: 1
Extra file open flags: 0
128 files, 16Mb each
2Gb total file size
Block size 16Kb
Number of random requests for random IO: 10000
Read/Write ratio for combined random IO test: 1.50
Periodic FSYNC enabled, calling fsync() each 100 requests.
Calling fsync() at the end of test, Enabled.
Using synchronous I/O mode
Doing random r/w test
Threads started!
Done.
Operations performed: 6000 Read, 4000 Write, 12800 Other = 22800 Total
Read 93.75Mb Written 62.5Mb Total transferred 156.25Mb (37.33Mb/sec)
2389.11 Requests/sec executed
Test execution summary:
total time: 4.1857s
total number of events: 10000
total time taken by event execution: 2.1715
per-request statistics:
min: 0.00ms
avg: 0.22ms
max: 9.18ms
approx. 95 percentile: 0.65ms
Threads fairness:
events (avg/stddev): 10000.0000/0.00
execution time (avg/stddev): 2.1715/0.00

Ab dem jeweils zweiten Durchlauf wurden die Werte deutlich besser.
Auf dem normalen VPS 200 laufen bereits diverse Dienste, die Last ist allerdings sehr niedrig.
Den vom BF habe ich extra für den Test gestartet, da läuft bisher nur der SSH-Daemon.
Beide Systeme Debian Buster mit Kernelversion 4.19.x.
