Hi Managers
I am looking to increase performance of Alphaserevr 1000A 4/266 box running 4.0f.
It has everything in it:
quite heavy math, high network untilization (X traffic and other),
also it has special PCI interface card, and application that works with it takes around 40% of CPU,
it's disk access intensive, too.
Sorry for the lack of details and logs.
We were given a very narrow window on the live system and performance was last on our minds.
The issue was discovered during last minutes, so that's all I have, info from "top".
The box has 512Mb memory with only 320Mb utilized, so the memory wouldn't be an issue.
At the moment I am thinking of the following:
1. Will use faster harddrive (10000rpm, LVD support) with SYM8952U Wide Ultra2 instead of internal SCSI controller.
This is easy to do for us, we have everything available except wide SCSI cable.
This would maximize disk access.
2. At the moment that PCI interface card is plugged into secondary PCI bus.
I wonder if replugging it into primary PCI bus would help somehow (it's bridged architecture),
so I'll do it anyway, it shouldn't hurt.
But we have general feeling that the task is simply over the head of 4/266 CPU we have
and it needs to be upgraded.
Unfortunately, I might be able to repeat the run and take good performance tests only in, at least, one week time...
Please, share your thoughts on this. Any info might prove to be helpful.
Thanks
