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:

Hi all, I recently started with Xen (3.1.0) on my new server running Ubuntu Gutsy (7.10) and I''m experiencing very poor network performance on my domU''s. Since my colo provider offers me a /28 of routed public IPs next to one interconnection IP to their routers, I built a Xen configuration as described in http://www.debian-administration.org/articles/360 (a routed

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? Kind regards Marek Wielgosz Bayes Consulting ######### Probably useful info ############### ### CPU: Core2Duo T 7300, 2 GB RAM ### WIN XP ### both standard

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

What really matters is not whether Wine has a Windows drive and filesystem to sit on top of, but whether or not Wine can use native Windows DLLs instead of its builtin ones. Some DLLs in Wine are so perfect that they can be used in Windows - no benefit will be gained from running an app that uses these natively. Some of Wine's DLLs are buggy or incomplete - using stock native Windows ones

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

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

Thanks for the reply Daniel, However I think you slightly misunderstood the scenario... On 14 November 2017 at 10:32, Daniel P.

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

Running samba with Ubuntu, default configuration, one share, samba running as daemons rather from inetd. Copying one file between 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

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.

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
