REDHATKVM compared to VMware performance, which will win more!

What's better about KVM and VMware single performance? The test information and results are as follows:

Physical environment

Memory 4G, CPU4, dynamic HDD 120G

Kvm:

HDD Test

Instantaneous read speed

Timing cached reads:23668 MB in 2.00 seconds = 11858.17 mb/sec

Timing buffered disk reads:294 MB in 3.02 seconds = 123.37 mb/sec

Read HDD 1G data speed

1024000000 bytes (1.0 GB) copied, 87.253 seconds, 11.7 MB/s

Write drive 1G data speed

1024000000 bytes (1.0 GB) copied, 10.5519 seconds, 97.0 MB/s

CPU Test

Second-level cache

Cat/proc/cpuinfo

Cache size:32 KB

Run a shell operation script 13 minutes

Cpu (s): 5.5%us, 0.6%sy, 0.0%ni, 93.3%id, 0.1%wa, 0.4%hi, 0.1%si, 0.0%st

Cpu (s): 0.1%us, 0.2%sy, 0.0%ni, 98.8%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st

Cpu usage in 0.1%~~5.5%, more evenly increase or decrease; memory and swap partitions are more stable

Memory Usage Test

Execute a memory-intensive program that runs for 3 minutes and consumes memory immediately to the maximum

mem:3945756k Total, 2854516k used, 1091240k free, 288700k buffers

swap:1020088k Total, 8k used, 1020080k free, 2278948k cached

mem:3945756k Total, 3919740k used, 26016k free, 12188k buffers

swap:1020088k Total, 100k used, 1019988k free, 3645968k cached

Vmware:

Instant Hard Drive read:

Timing cached reads:24068 MB in 2.00 seconds = 12058.10 mb/sec

Timing buffered disk reads:790 MB in 3.00 seconds = 263.06 mb/sec

Read HDD 1G data speed

1024000000 bytes (1.0 GB) copied, 70.1827 seconds, 14.6 mb/s

Write drive 1G data speed

1024000000 bytes (1.0 GB) copied, 4.5338 seconds, 226 MB/s

CPU Level Two cache

Cat/proc/cpuinfo

Cache size:8192 KB

Run a shell operation script 10 minutes

Cpu (s): 4.9%us, 0.7%sy, 0.0%ni, 94.1%id, 0.1%wa, 0.0%hi, 0.1%si, 0.0%st

Cpu (s): 0.0%us, 0.0%sy, 0.0%ni, 99.7%id, 0.2%wa, 0.0%hi, 0.0%si, 0.0%st

CPU Usage

Cpu usage is 0.1%~~4.9%, there is little fluctuation; memory and swap partitions are stable

Memory usage

Execute memory-intensive program, execution time 5 minutes, slow memory consumption to maximum

mem:4044464k Total, 2974892k used, 1069572k free, 56892k buffers

swap:1020088k Total, 16k used, 1020072k free, 2605660k cached

mem:4044464k Total, 4016472k used, 27992k free, 12296k buffers

swap:1020088k Total, 116k used, 1019972k free, 3692420k cached

Sum up:

KVM memory usage efficiency is high, hard disk write speed is slow, CPU utilization is stable, also low

VMware memory usage is not high, hard disk read and write fast, high CPU utilization

The overall performance of KVM and VMware is not visible from data last data, and after multiple tests, VMware can perform much better than Redhat's KVM performance.
