Performance Grades

To summarize the performance of each VPS plan, we generated grades based on the various tests that were run: web, sysbench, endurance and remote timing tests. Each grade focuses on one aspect of the VPS speed or stability (cpu, disk IO, network IO...) and is made of one or more metrics measured during the tests.

Grades are evenly distributed between A and F. A is best, F is worst.

Follow the letter links to find the test results backing the grade.

How are grades calculated?

The grades above are based on the following test results.

Web Response Times

We ran a database intensive web application with ~100,000 hits per day for several days on cloud servers from BuyVM and Kamatera. This is the average response time measured locally on the VPS for each plan we tested.

Local Response Time per Plan

Lower is better

Provider Plan Average response time
BuyVM Slice 1024 101.0ms
BuyVM Slice 2048 103.0ms
Kamatera Availability 1GB 1core 73.0ms
Kamatera General 1GB 1 core 63.0ms
Kamatera General 1GB 2 cores 64.0ms
Kamatera General 2GB 4 cores 80.0ms

During the Web Test, we collect response time metrics, CPU metrics and database performance metrics. All of those are measured locally on the VPS running the web server. All metrics can be compared on the Web Performance Comparison page.

Sysbench CPU Performances

We ran the full suite of Sysbench tests on VPS plans of BuyVM and Kamatera. These are the Sysbench CPU test results:

Rate of operations

Higher is better

Provider Plan Operations per second
BuyVM Slice 1024 370.1
BuyVM Slice 2048 384.4
Kamatera Availability 1GB 1core 395.2
Kamatera General 1GB 1 core 391.7
Kamatera General 1GB 2 cores 817.5
Kamatera General 2GB 4 cores 1318.2

Sysbench test results are also available for random disk IO tests, sequential disk IO tests and memory tests.

Remote Timings

During the entire duration of the web performance test, we collected web response times from 5 different locations in the world. The chart below reports the connection establishment time + TLS handshake latency from all 5 locations. (That excludes the time spent on the server that is already measured in web response times above and it also excludes the DNS resolution time since it is not dependent on the provider).

Remote Latency per Plan

Lower is better

Provider Plan Average remote request duration
BuyVM Slice 1024 356.0ms
BuyVM Slice 2048 481.0ms
Kamatera Availability 1GB 1core 333.0ms
Kamatera General 1GB 1 core 494.8ms
Kamatera General 1GB 2 cores 347.6ms
Kamatera General 2GB 4 cores 341.8ms

Detailed remote timings measurements including connection time, TLS handshake time, and response time can be compared for BuyVM and Kamatera on the Remote Timings Comparison page.

Network Transfers

We have performed large file transfers from the BuyVM and Kamatera VPS and we measured the speed of downloads and uploads.

The transfers involve multiple files, 10 threads and last for at least 10 seconds at maximum speed. The transfers are repeated 3 times from different servers and only the fastest transfer is reported here.

Download Speed per Plan

Higher is better

Provider Plan Network Download Speed
BuyVM Slice 1024 683.2Mbps
BuyVM Slice 2048 164.6Mbps
Kamatera Availability 1GB 1core 1428.2Mbps
Kamatera General 1GB 1 core 2146.9Mbps
Kamatera General 1GB 2 cores 1006.4Mbps
Kamatera General 2GB 4 cores 1051.5Mbps

Network Transfers measurements including download and upload speeds can be compared for BuyVM and Kamatera on the Network Transfers Comparison page.

Sustained CPU Endurance Tests

We pushed the CPU of those VPS plans hard for 24 hours straight.

This test shows how fast the VPS can go for long periods of time, how stable the performance is and it also gives clues on how overallocated the VPSs may be.

Average number of operations per hour

Higher is better

Provider Plan Average ops/hour
BuyVM Slice 1024 1820.8
BuyVM Slice 2048 1715.7
Kamatera Availability 1GB 1core 2225.8
Kamatera General 1GB 1 core 1630.8
Kamatera General 1GB 2 cores 4549.5
Kamatera General 2GB 4 cores 5307.4
