Hi Thomas,

 

I gave it a shot and it's really nice. I've got one question though concerning the 'support for dynamically linked executables' feature: does it mean that we don't have to set the MINIXDYNAMIC flag to yes anymore when installing something from pkgsrc and want to have shared libs?

 

Thanks&regards,

r0ller

I remember 'make servers' was about 5% faster on intel (sysenter). the effect was bigger on vmware if the TSC-based timing within vmware is to be trusted.

You can try to time it yourself by turning libc_ipc=1 on/off (kernel boot messages about the selected/forced IPC style will tell you whether it had the desired effect) and using the worldstone script.

Thank you for the info, Ben! 5% is pretty good improvement.
