I made some simple comparisons about CPU usages between running Wine and running XP on a VirtualBox. In both cases, I ran exactly the same 2 applications with about the same configuration. The Wine I use is 1.3.26. The XP is XP Home with SP2 but trimmed down to nearly its bare-bones (having only the possibly minimum number of services running). The computer is a Dell Studio laptop with

The VMCI handle array has an integer overflow in vmci_handle_arr_append_entry when it tries to expand the array. This can be triggered from a guest, since the doorbell link hypercall doesn't impose a limit on the number of doorbell handles that a VM can create in the hypervisor, and these handles are stored in a handle array. In this change, we introduce a mandatory max capacity for handle

As far as I can tell rsync doesn't support this. How hard would it be to implement this? Is it trivial enough to just change the calls in the code with sed? I think this can significantly reduce CPU usage and increase I/O speed when dealing with fast storage solutions. It can make a huge difference when say transferring 30TB of data. Here are some tests I did. So far the only thing I know

Hi, We are running java application on centos4 update 5 64 bit on sun blade x6250 hardware.But for the last couple of days we observed that kacpid daemon eating more cpu.Attached the top output below.Can any one suggest me how to fix the same since it is my critical production i need your help urgently . Top output PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 27

Hi, i have a vm which has a poor performance. E.g. top needs seconds to refresh its output on the console. Same with netstat. The guest is hosting a MySQL DB with a webfrontend, its response is poor too. I'm looking for the culprit. Following top in the guest i get these hints: Memory is free enough, system is not swapping. System has 8GB RAM and two cpu's. Cpu 0 is struggling with a

Hi all, I have a question about memory usage and IPC$ share. I'am auditing the swap usage of my server because I already have a problem with a full swap. I see that the smbd process take < 200Mo on swap : Example : PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 24429 lge 15 0 197m 39m 14m S 0.3 1.0 0:15.17 smbd but some process use more than 200Mo

Hello list, how could this happen? The Server doesn't respond from time to time with a high load avarage. We found a suspicious smbd process: top - 13:43:07 up 1 day, 2:27, 5 users, load average: 32.49, 58.41, 37.95 Tasks: 1196 total, 5 running, 1190 sleeping, 0 stopped, 1 zombie Cpu0 : 14.7% us, 3.8% sy, 0.0% ni, 79.8% id, 1.3% wa, 0.0% hi, 0.3% si Cpu1 : 1.3% us, 84.6%

Is there something unusual about the way BATCH jobs are run? I ran a job like this: nice R CMD BATCH program.R It ran for a little while and then it starting eating up huge amounts of resources.

I'm running into a memory problem when trying to switch some web servers that are running centos4.8/x86_64 to centos5.5/x86_64. The new servers running centos5.5 are using a decent amount more memory than the centos4.8 servers. Here's an example from top: --- centos 5.5 --- $ uname -a Linux ws51 2.6.18-194.17.1.el5 #1 SMP Wed Sep 29 12:50:31 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux

I'm not sure what gave me this idea, but I decided to comment out the swap partition in /etc/fstab and reboot my laptop. I did not run swapoff directly at any time. I'm running more things now than I would ever dream of to hammer my 500MB of memory, but I still notice NO slowdown. This is the best desktop experience I've ever had for any OS on any hardware! Here's the first 12

Hi all, I am trying to tune and troubleshoot an application which runs a background (delayed_job) process involving the import and processing of large csv files into the db and then processing of that data. When I run the process (here Ubuntu 10.04) and monitor ''top'' in the terminal, I see that ''Mem: used'' starts at maybe 500000k and then ups through the process

xenconsoled: do not write the pty under serial in xenstore if xenconsoled is handling a consolepath. The idea is that pv consoles use the "console" prefix in xenstore and emulated serials use the "serial" prefix in xenstore. There is no need to write the pty for a pv console under "serial", considering that xenconsoled is already writing the pty under

Hello, I have run into some performance issues after adding bricks to a 3.3.1 volume. Basically I am seeing very high CPU usage and extremely degraded performance. I started a re-balance but stopped it after a couple days. The logs have a lot of entries for split-brain as well as "Non Blocking entrylks failed for". For some of the directories on the client doing an ls will show multiple

I'm working with a very large matrix ( 22k rows x 2k cols) of RNA expression data with R v.2.5.0 on a RedHat Enterprise machine, x86_64 architecture. The relevant code is below, but I call a function that takes a cluster of this data ( a list structure that contains a $rows elt which lists the rows (genes ) in the cluster by ID, but not the actual data itself ). The function creates two

Hi all, I''ve been having trouble for a long time with backgroundrb processes that suddenly vanish without a trace. What happens is that at some point I discover that all the backgroundrb processes are suddenly gone. Nothing special is seen in any of the log files. This has happened intermittently for a long time, and I was hoping that upgrading to 1.0.4 would somehow help me out, but
