colima oracle-xe very slow

Description

Hi I might be doing something wrong but i have a full spec mac m1 max and I ran following

colima start --arch x86_64 --cpu 8 --memory 8 --disk 5

docker run -d -p 1521:1521 --cpus="8" --memory=4096M -e ORACLE_PASSWORD=test -e APP_USER=test -e APP_USER_PASSWORD=test -v oracle-volume:/opt/oracle/oradata gvenzl/oracle-xe

When I run my java app it basically cleans all table and add new tables, whole thing used to take 20 sec on my windows machine. Now takes 2 minutes.

I've tried increasing cpu because when i run

docker stats

I see the cpu is spiking under load, 100-500%, ive tried increasing to 16 cpus but no difference in total time execution.

I'm starting to suspect if it's network related?

Expected behaviour

No response

Additional context

That is because you are emulating x86_64 on your m1 device. That is expected.

@abiosoft does colima use 'fast' or 'slow' mode for running the linux host? https://github.com/lima-vm/lima/blob/master/docs/multi-arch.md

[abiosoft]

@quom you decide.

According to the linked Lima doc, if you start colima with non-native architecture, it is slow mode.

# m1
colima start --arch x86_64 # slow mode

# intel
colima start --arch aarch64 # slow mode

If you start colima with native architecture, but only specify custom arch with docker (or containerd), it is fast mode.

# m1
docker run --platform linx/amd64 gvenzl/oracle-xe # fast mode

# intel
docker run --platform linx/amd64 gvenzl/oracle-xe # fast mode

Kindly bear in mind that there is no fast mode per se on cross-architecture, the performance will be notably degraded. What is however faster is the VM performance.

The slow mode will have a slow container and VM, while the fast mode will have only a slow container but a performant VM.

@abiosoft fixed a small typo in platform paramter:

# m1
docker run --platform linux/amd64 gvenzl/oracle-xe # fast mode

# intel
docker run --platform linux/amd64 gvenzl/oracle-xe # fast mode
