similar to: mail open slowly

Hello, I upgraded my dovecot server (1.2 -> 2.1), from debian backport because it was a little slow (wait 5-6 sec) when I opened some mail (but not every mail). Unfortunately, the mail open speed didn't increase. I think it's an index problem. Have you idea for fixing?

"to memory" means: mounting a ~2 GByte filesystem [ tmpfs?, or ramfs? ], and put the "/tmp" on it. [ e.g.: 4 GByte ram in the pc ]. what to write in the "/etc/fstab"? I would like to collect the [ answers too:P ]: Advantages: - Memory is way faster then HDD/SSD, so it could speed things up - "SSD amortization" is less Disadvantages: - Security?

Hi everyone, I'm trying to use samba in a small video post production house but we are not getting the performance we expected. Our setup: - CenOS 5.6 x86-64 - samba.x86_64 (3.0.33-3.29.el5_6.2 and 3.6.0rc1) - Intel based server (One 4 core Xeon E5620 @ 2.40GHz, 8 GB RAM) - 4 Intel Gigagit ethernet NIC ports with 802.3ad bonding connected to a switch configured tu use 802.3ad - 8 2TB 7.2

Hi, I'm trying to make a ts object that has both NA values and a frequency other than 1 (so I can use stl). I've tried all permutations I can think of, but cannot get the desired (expected?) results. The values live in x and the corresponding semi-regular time stamps are in t: > library('zoo') > z = zoo(x, order.by=t, frequency=24) > zzr = as.zooreg(z, start=0) > zr

I am working with some large text files (up to 16 GBytes). I am interested in extracting the words and counting each time each word appears in the text. I have written a very simple R program by following some suggestions and examples I found online. If my input file is 1 GByte, I see that R uses up to 11 GBytes of memory when executing the program on a 64-bit system running CentOS 6.3. Why is

Reading a flat text file 138 Mbyte large into R with a combination of scan (to get the header) and read.table. After conversion of text time stamps to POSIXct and conversion of integer codes to factors I convert everything into one data frame and release the old structures containing the data by using rm(). Strangely, the rm() does not appear to reduce the used memory. I checked using

Hello all, I am having problems with memory when running R on my PC. I do not have many large objects in my workspace, and yet when trying to create a new vector I often encounter this error message: > lat <- header$lat[match(profile$id, header$id)] Error: cannot allocate vector of size 4575 Kb Since it seems like this may indicate that I don't have enough memory available, I

Dear members, It may sound a silly question. I have curl installed: # pkg_info |grep curl curl-7.24.0_3 Non-interactive tool to get files from FTP, GOPHER, HTTP(S) Today portsnap updated the ftp/curl port, and patch-CVE-2013-2174 appeared in files/, but the port version remained such that portaudit, and portupgrade still complain about curl's version. What is the recommended way to

How can I slow down dd? I don't want to slow down the pc, when generating a big file [~40 GByte]. Does ionice work properly? Thank you for any help! :\

Hi folks, We ran 2 mirror jobs using "rsync -av remote:/from /to" of appr. 700 GByte. Problem: On the second run about 10 or 15 files were copied again, even though we are very sure that there was no service running which could have changed the files on remote:/from or on /to. Esp. Samba and NFS were off. How comes? The remote host has rsync version 3.0.4. The localhost uses version

Hi folks, I have to migrate a set of iscsi backstores to a new target via network. To reduce downtime I would like to mirror the active volumes first, next stop the initators, and then do a final incremental sync. The backstores have a size between 256 GByte and 1 TByte each. In toto its about 8 TByte. Of course I have found the --copy-devices patch, but I wonder if this works as expected? Is

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello everybody, I have one thousand virtual users with mdbox mailbox format and 10 GByte quota.

Hello, I own one of these netbooks Asus Eee PC 900, mine is running FreeBSD 7.0, and a Linux based cellphone, the OpenMoko Freerunner. Since some time I'm thinking in a replacement of my 'normal' BRI phone at home and the two items mentioned above let me think that the replacement should be UNIX based as well. The legacy BRI phone, around ten years old, even has more or less the same

Hi, I am running Samba version 3.0.22 for a small office where the clients are windows 2k and XP machines. basically everything works OK and the only problem I am facing now is that it takes ages before windows opens samba shares. I tried turning off web client in win xp which helped a little but it is still too slow. It takes almost 7 minutes to copy a 2G file to a windows machine from linux
