Hello, can anyone give me some tips why the file size of various samba executables has been increased dramatically from 3.0.34 to 3.3.3 (e.g. smbd 3.5MB -> ~7MB) The reason is that it is necessary for our project to keep the size as small as possible. You can have a look into the makefile here: http://freenas.svn.sourceforge.net/viewvc/freenas/experimental/samba3/Makefile?revision=4553&view=mark...

...s expected: all domU''s are accessible from the internet. The network performance of the Dom0 is fine: I can saturate my 100Mb/ sec uplink both by uploading and downloading. Performance towards the domU is fine as well. Performance from the DomU''s to the internet however is dramatic: speeds start at 2-3MB/sec but quickly drop to just a few KB/sec (!). Transfer of large files never end at all. The server I''m running this on is a Supermicro H8SSL-i2 with and AMD Opteron 1218 Dual Core proc, 4GB RAM, the NIC is a Broadcom 1G interface connected to a 100Mb/sec swit...

Dear R users/developers, simple comparison of code execution time of R 2.7.1 and R 2.7.2 shows a dramatic slowdown of the newer version. Rprof() identifies .Call function as a main cause (see the code below). What happened with R 2.7.2?

Hi all, I have been a Wine user since about 2002 and have even contributed a few simple patches, but this is my first time on the forum. Anyway, I just wanted to make it known that wine 1.3.20 provides a dramatic increase in performance. Scrolling in the iTunes Music store no longer reminds me of pouring molasses (finally) and Photoshop Elements 5 is usable. Does anyone know what the magic was and if any more of it is possible? This is amazing! -Matthew

I hope someone here knows the answer to this since it will save me from delving deep into documentation. Based on 22 pairs of vectors, I have noticed that tetrachoric correlation coefficients in stata are almost uniformly higher than those in R, sometimes dramatically so (TCC=.61 in stata, .51 in R; .51 in stata, .39 in R). Stata's estimate is higher than R's in 20 out of 22 computations, although the estimates always fall within the 95% CI for the TCC calculated by R. Do stata and R calculate TCC in dramatically different ways? Is the handli...

True, I just hoped you or one of the other devs might have some insight on reclaim behaviour that would provide a clue. I guess I'll try a

Hello, all Is there anyone interested in the performance of USB under QEMU? I found that when use OHCI to replace UHCI in qemu, it will improve the performance of USB storage device. I have tested it, the performance is almost equal of a real usb device. The way to do this is making little change in the file xen-3.1.0-src/tools/ioemu/hw/pc.c . --- pc.c.original 2007-08-14

During norml operation this morning we're seeing a significantly increased load on the IMAP server (factor 5, from 5 to 25). Does dovecot need to rebuild index files or perform other IO intensive operations after the upgrade? We're using Maildir Our monitoring shows increased "system" time. We're runnign fewer processes, the IO rate ist identical to yesterday, memory usage

Hi all, I'm using Wine for a MotionCapturing Application (Qualisys). Although it's a quite recent application, it works well (I tried only data processing so far), but when I try to save a dataset (~180MB), it takes about 20 Minutes (!!) on my Computer. When I use it under VirtualBox (it does not run nicely there because of OpenGL), saving takes about 20 seconds. When I look at

I wondered the same thing, especially in the context of someone who prefers virtual machines. LV-backed VMs have *dramatically* better disk performance than file-backed VMs.

There are options that can help a little bit with the ls/find. Still, many devs will need to know your settings, so the volume's info is very important. Try the 'noatime,nodiratime' (if ZFS supports them). Also, as this is a new cluster you can try to setup XFS and verify if the issue is the same. RedHat provide an XFS options' calculator but it requires aby kind of subscription

...etween the share and another machine on the LAN is very slow. Adding another copy and both transfers proceed very quickly. The client machines are Macs with recent OSX, and a Windows laptop. Same behavior. If the second transfer is initiated on a different client, both transfers still speed up, dramatically. Any ideas? Thanks in advance.

Hi all I'm running since a couple of years a samba ver 3.0.33-3.29.el5_6.2 On a Red Hat 5 with kernel 2.6.18. Samba is member of a domain, with short name BNNAS03; some shares are using domain users, some are anonymous, open to a list of IPs. Suddenly is happening that, from my win7 computer is all ok if I call is with \\bnnas03 I see all shares, I can access and so on. If I call with

Hi guys, I know it's a little off topic but......Wondering if you can help. My wife has been asked to find a writer to produce a story on "The dramatic ramifications of IPV6 on commercial businesses and how it will change the product designs for ordinary household/commercial use in a 5-10 year time frame" So her company hired someone who should have been able to deliver the goods (ex magazine editor - maybe a little too 'ex'....)...
