Hi, My name is Luo Zengbo, a student from Zhejiang University, China. As I mentioned in IRC before(my IRC nick name is poe_), I am interested in GSoC project: Speed up the Test Suite. After discussed with Olly, I think this project can be divided into three steps: Step 1: Rewrite every call of the function get_writable_database(). I will pass writable database's name with

Hi all: I've written a function and saved the worksapce.When the workspace of my function is re-open,I want display some introduction or step by step guidance of the function for the users.How can I do it? Thanks a lot! My best regards!

Hi! I have some strange results on my test with nouveau drivers I'm using a old GeForce4 MX 4000 (NV18) with 128 MB. I have made 2 test. -The default configuration, using nomodeset without nouveau_vieux_dri.so $inxi -G Graphics: Card: NVIDIA NV18 [GeForce4 MX 4000] X.Org: 1.12.4 drivers: vesa,nouveau (unloaded: fbdev) Resolution: 1024x768 at 0.0hz GLX Renderer: N/A

Hi all, I was wonder what experiences there are out there with using RAID-X for performance increases. I do use RAID-1 (2 disks) but am interested in attemtps to gain higher R/W performance. Do the RAID-5's etc give noticeable performace increases? A significant help for me was using ccache for compiling programs. That was a real performance increase. Thanks for any suggestions/opinions.

Hi, please help... In controller... def index @customers = Customer.find(:all) pagination code here.... end In index.html.erb Displayes list of customers and has pagination 1,2,3,4...etc. On clicking page 2, it will again run this(Customer.find(:all)) query in controller. So, there will be lack of performance. So, how to increase the mysql performace? Can i use the index as below or any

Hi, I am a Masters student from Carnegie Mellon University. I am looking for a research topics for an Advanced OS & DS course we have. I wanted to know what is the current support for NUMA on Xen ? Does it support the IBM x440 and AMD64 Opteron ? Also, does the Xen scheduler do NUMA aware scheduling so it does not degrade the VM performace ? My group is currently looking into Scheduling

change from v2: __spin_yeild_cpu() will yield slices to lpar if target cpu is running. remove unnecessary rmb() in __spin_yield/wake_cpu. __pv_wait() will check the *ptr == val. some commit message change change fome v1: separate into 6 pathes from one patch some minor code changes. I do several tests on pseries IBM,8408-E8E with 32cpus, 64GB memory. benchmark test results are below. 2

Hi folks In linux kernel development, there is a debug tool called dprobe ,which can be used to dynamic insert the probes into the function of kernel source code and find what''s goning on.There is also a tool called systemtap which is based on dprobe and kernel debug info. Using the kprobes infrastructure, SystemTap is being developed to dynamically instrument the kernel and user

Hello, i have just migrated machine to xen server where only 2 cpus are available. I have copied config from machine where domU was located before. That machine had 4 CPUS (QUADCORE), current machine has 2 CPUS (1 XEON 2cores). I have forgot to change vcpus from 4 to 2 in config, but .. what really surprised me ... machine started . How it is possible? It was really slow alltought and not

Hi forks: I've been testing SMB2 with samba 3.6.4 performance these days, and I find a weird benchmark that SMB2 write performance is slower than SMB1 in 10Gb ethernet network.

Hi, I have a strange phenomenon that I cannot readily explain so I wonder if anyone here can shed a light on this. The host system is a Dell r815 with 64 cores and 256G ram and has centos 6 installed. The five guests are also running centos 6 and are running as a hadoop cluster. The problem is that I see disk-io spikes in the vm's which then cause soft lockups in the guest but I also see

Hello, First of all, i am new at the list and i have several questions about ocfs2 performance. Where i am working i am having huge performance problens with ocfs2. Let me tell my envoriment. 3 Xen VirtualMachines withs ocfs2 mounting an LUN exported over iSCSI. ( acctualy 3 LUNS, 3 ocfs2 clusters ) I am not the one who configured the envoriment, but it is making the performance of my MAIL

Hello, I'm doing bootstrap in R 2.4.1 in order to compute standard errors of an estimator. I'm running the same program on 4 computers. The core of the program is a nlm minimization of a function, which is (I believe) nicely coded using (t)apply and all the vectorized stuff. I'm slightly puzzled by the differences in the speed of computation. The program works twice as fast on a

Issue: Vista reads slowly from a samba server. This appears to pop up periodically here and elsewhere. My samba.conf file has: [homes] ... vfs objects = readahead As suggested elsewhere. Writes are approximately 17-18MB/s which is acceptable. Reads are in the 8MB/s range which is appalingly slow. Using linux smbclient and windows XP clients I can read at 25+MB/s. I've enabled vfs
