Re: Cygwin allocted time slice

'time' results confirm this.  Process time is about 1/4 of the total
system time.

It i very noticable on compiling and testing GCC as compared to the
same on Linux or MinGW.

Is there any way to give Cygwin a bigger slice of the pie ?

Say 50% or 75% ?

How do you suppose Cygwin is managing this interesting feat of only using some of the CPU time? What Windows API is Cygwin using to just grab a small slice of the time?

Weird I was getting very long compile times for GCC and on using 'time' was getting indications that make was only getting 25% of total system time.

I'll see if it is repeatable on another system.

As a follow-up question:  Why do you suppose we are punishing you by
not allowing Cygwin to use all of the CPU by default?

Oh. Wait. WJM. Nevermind.

Weird reply, no need to take the micky !
