HI all,
I have one compaq server with 4 Intel(R) Xeon cpu's (3.1GHZ), 4GB RAM.
OS:- Fedora Core 2
Kernel:- 2.6.14
when i compile a new kernel, during th compilation process load goes
very high (10 and little above). i can not understand why does this
happen, while if i compile the same kernel on my P4 machine with 1GB ram
and 3GHZ, it remains under 3.
can somebody tell me what is wrong?

Sounds suspiciously like DMA is not working on your drives. Check your dmesg
logs and what hdparm returns.

Hi,
hdparm -tT /dev/cciss/c0d0p2 returns the following
/dev/cciss/c0d0p2:
Timing buffer-cache reads: 2660 MB in 2.00 seconds = 1329.92 MB/sec
Timing buffered disk reads: 248 MB in 3.00 seconds = 82.55 MB/sec
if i try to hdparm -I /dev/cciss/c0d0 it returns
/dev/cciss/c0d0:
operation not supported on SCSI disks
Do i need to installed sdparm and modify some settings?

Timing buffer-cache reads: 2660 MB in 2.00 seconds = 1329.92 MB/sec
Timing buffered disk reads: 248 MB in 3.00 seconds = 82.55 MB/sec
if i try to hdparm -I /dev/cciss/c0d0 it returns

it's expected ;)

With or without a following integer?
See 'make help':
-j [N], --jobs[=N] Allow N jobs at once; infinite jobs with no arg.
so use make -j N to limit the number of makes/compiles etc.
or use 'make -j' to go ballistic.
