Hi, I'm running samba 3.0.23c on Solaris 10. The smbd processes on my PDC have increased in size from 7Mb to upto 86 Mb , the majority of which seems to be resident . 3940 root 77M 72M sleep 59 0 0:00:01 0.1% smbd/1 14174 root 77M 73M sleep 59 0 0:00:10 0.1% smbd/1 13551 root 77M 73M sleep 59 0 0:00:18 0.1% smbd/1 19888 root 77M

...are stored on separate NFS servers because files are accesses by our users from either linux or windows systems. So a write to this samba server always will read or write files from/to NFS servers. The problem is speed when many very small files are copied from windows. I have a test directory of 70MB in size consisting of 5528 mostly very small (<=70Kb) files. The directory is stored on a local disk on the windows machine. "Copy via smb" below means, I copy the data from a Windows 10 VM to a share connected on the smb server (which results in writing the data on the NFS file server...

System: PIII 500Mhz 128MB memory 20GB drive Current CentOS 4.2 Gnome GUI The system runs 'idle' at around 70Mb memory used and 4% cpu usage. But whenever I go to start a task: Start Gedit, Services tool, a Terminal window, Firefox It takes a minute or so. CPU mayyyypeak at 100% briefly then come down. Memory has yet to exceed 100Mb usage. Any pointers of where to look to see why it is slow?

I have a Windows 7 laptop that I want to make dual boot with CentOS 6.2. My plan was to use the Windows Disk Management tool to partition the disk, but I do not have the needed admin rights on the box to use that. Has anyone used the partitioning tool that comes with 6.2 to do this? Can I have some level of confidence that it will not mess things up so that I cannot boot into Windows? if it screws

...9;m getting around 10mb/s write performance. :-( I'm seeing high iowait figures at times and associated very high cpu load average figures, probably because, under load, everything is stacked up waiting for the disks to actually do something. A non-raid sata disk in the same machine manages 70mb/s Does anyone know what the performance is like if I used the 3ware just as an IDE controller? I could then switch to software raid5?

...ogical volumes for its disk, so I am using virtio. I got the iso in http://alt.fedoraproject.org/pub/alt/virtio-win/latest/images/bin/images/, but how do I feed it to the XP install? I did try to mount it as a floppy and it hung there on "please wait"; I guess that means it did not like a 70MB iso as its floppy. But it also does not seem to want to look for the drivers if I mount the .iso as a CD. What else can I try?

...nd have run into write performance issues with the NFS server. time dd if=/dev/zero of=/home/testfile bs=16k count=16384 268435456 bytes (268 MB) copied, 45.0461 seconds, 6.0 MB/s This is much too slow for the gigabit network. We can improve this a lot by exporting /home with the async option (60-70MB/s), but the NFS documentation strongly recommends against using async (opposed to sync) because of possible firesystem corruption if the NFS server crashes. This is a cache issue. After numerous tests we have given up trying to get it working properly. And we've been trying CIFS. Everything wo...

It looks like the profile data file generated by llc contains approximately 5MB of counters (__llvm_prf_cnts), 10MB of "data" (__llvm_prf_data), and 70MB of __llvm_prf_names. __llvm_prf_data and __llvm_prf_names contain which can be read from the original binary, as far as I can tell. The 80MB of data wouldn't be a big deal if it were just sitting on disk... but we also erase the whole file and rewrite it from scratch after we merge profil...

...00KB/s throughput to the disks. Even with 24hrs of fsck-ing I only get ~3% (still in pass1). The filesystem is ext3 running "e2fsck -C0 /dev/sda3" and about 3.7TB on an x86_64-based system with 4GB RAM. e2fsprogs is 1.41.9. During initial periods of the fsck I see throughput in the 30-70MB/s range (ie, <0.4% complete). Shortly after that throughput tanks and stays there. Just a rough extrapolation of the size of my filesystem (3.4TB used; ~95%) makes it look like this will take ~28 days to complete. I'm using approx 12M inodes out of my 243M available. -Doug --------------...

Hi, folks. I'm new to both Ubuntu Linux and Wine. I've been running Lotus Ami Pro for years under Windows 98 and have about 70MB of Ami Pro files. Nowadays, though, printers are not made to support Windows 98 anymore. I had heard about WINE, and rather than buy another Microsoft product, I decided to see if I could run Ami Pro under another OS. My new printer works perfectly under Linux, so that's not a problem. Abiw...

...between nodes "dd" performance: 400mb/s and higher Downloading a large file from internet and directly to the gluster: 250-300mb/s Now same test without Stripe but with sharding. This results are same when I set shard size 4MB or 32MB. (Again 2x Replica here) Dd performance: 70mb/s Download directly to the gluster performance : 60mb/s Now, If we do this test twice at the same time (two dd or two doewnload at the same time) it goes below 25/mb each or slower. I thought sharding is at least equal or a little slower (maybe?) but these results are terribly slow. I...

...policy for excluding the directories from the roaming profile. Everything is working properly AFAIK except for one thing, when the user logs out, Windows XP displays a dialog with a progress bar and says its syncing the profdata share. If I copy a big file to the Desktop, say something around 70MB, this sync takes a long time, like it's copying the file to the server or off the server or something. The registry key for the "User Shell Folders\Desktop" is set to \\%LOGONSERVER%\profdata\%USERNAME%\Desktop and I have Desktop as one of the folders in the "Exclude from roa...

...el module and some tools from a repo at lfarkas.org (unfortunately the new virt-manager there cannot be installed due to depency issues) to experiment with KVM which works so far but gives me weird results. Doing a "hdparm -t" on the host system consistently gives me a result of about 70MB/sec yet in a KVM guest I get results ranging from 40MB/sec to 125MB/sec on each run. Also the Centos kernel does not support the virtio drivers needed for KVM paravirtualization so I'm wondering how fast hardware assisted block-io under KVM is compared to the performance of the paravirtuali...

Dear R-user, I'm running a certain R script in DOS batch mode. Is there a way to prevent R from saving the workspace once this script is finished? I'm asking this because the resulting .RData file has the size of >70MB. I don't need this file since my script already writes the required output and this makes the whole process very slow (>15 minutes each time) FYI, my script: setwd("M:/Program Files/Soskat/Models") library(randomForest) CT <- read.table("CRD.txt",header=TRUE,sep=&qu...
