Hello all, I have 2 identical Dell r510 servers with 10gig card, running centos 6 with samba-3.5.4-68.el6_0.2.x86_64. I setup 16G ramdisk samba share on both and ran cp from local ramdisk to samba ramdisk mount. If I cp 12 1-gig files, I get combined 100MB/s transfer rate. Single file cp maxes out at about 15MB/s. Ftp transfer give me over 300MB/s. Running with 9000 MTU. Most smb.conf is

I have 4 gig in my * box. I'm tuning for performance and I'd like to ask opinions: 1. asterisk -p == renice -20 ?? 2. I've turned off swap with no apparent ill effects. Can anyone commment on long term effects with moderate load (say, 30 SIP phones / 2-3K calls /day) 3. Can anyone comment on using ramdisk as swap and whether this is a good idea or bad idea? I'm using 2.6

Hello We are using dovecot 1.2.x. In our setup we will have 1200 concurrent imap users (maildirs) and we have 2xraid5 sas 15k diks mounted by iSCSI. The dovecot server (RHEL 5 x64) is a virtual machine in our vmware esx cluster. We want to minimize disk I/O, what config options should we use. We can "exchange" CPU & RAM to minimize disk i/o. Should we change to dovecot 2.0?

Hi, I have buit Xen (32 bit) with PAE and can start multiple Paraguests with 4 gig memory, but cannot launch a single VM with more than 4 gb memory. I would like to launch 1 VM with 30GB or so memory. Are there any config paramters like kernel,/inittrd that need to be changed. I have the ramdisk set to the initrd I used to boot xen with PAE. Thanks - padma

Hello, I have a problem with a 2.5.62 kernel and ramdisk. I am using isolinux to create a cd that loads some of its partition in ramdisk. The script involves mounting a ramdisk (e2fs) on /fake/ramdisk, copying part of the cd to that mount point, unmounting it, and remounting it on /fake/needwrite. The problem is that, although the content of /fake/needwrite gets correctly copied, the content of

I?ve got a 512M machine and a 330M ( uncompressed ) initrd image. How can I mount the ramdisk? Normal booting seems to want to copy the entire initrd image into a Ramdisk, thus requiring 2X the memory. So what happens is the kernel boots correctly and I get, RAMDISK: ext2 filesystem found at block 0 RAMDISK: Loading 330000 blocks [ 1 disk ] into ram disk And then I never see the light of day after

Hello All. I have five Centos 4.4 x86_64 (amd fx-62) boxes with 4 gig of Corsair dual channel ram running kernel 2.6.9-42.0.10.EL (smp). The sixth box is the same except for video card and ram. It is using 8gig of GSkill dual channel ram and has a very cheap ATI video card in it. This box will segfault on boot unless I use noapic acpi=off and nolapic. Even with these boot params, the box is not

Hi there, I am new to Xen. Just began trying it out from day-before. I have a CentOS 4.4 install on my hda6 partition. And I have a openSUSE 10.2 install on my hda8 partition.
