similar to: Some benchmarking

I wasted too much time today doing this, but they do show a few interesting things: 1) mmap_disable=yes is faster than mmap_disable=no. I didn't expect this. I'm not yet sure why this is, but possibly because then it updates the mail index by reading the changes from dovecot.index.log, instead of reopening and re-mmaping dovecot.index. At least that's the biggest difference between

v2.2.19 has many fixes related to dsync+imapc, which were found while migrating several million users from GMail. I'm not aware of any problems with it now. Also even before v2.2.19 dsync+imapc has been used to successfully do many large migrations. > On 26 Nov 2015, at 17:49, FUSTE Emmanuel <emmanuel.fuste at thalesgroup.com> wrote: > > Hi, > > No, I tried fetching

SEARCH is probably the slowest command that Dovecot has, especially when searching texts from message bodies. There exists a lot of text search engines, but unfortunately as far as I know there exists only one that can be used with IMAP. The reason why IMAP is special is because it requires that when searching eg. "ello", it must match also mails which contain eg. word

There's now a plugin called lazy_expunge in CVS. Instead of EXPUNGE expunging the mails directly, they're moved to a mailbox with same name in another namespace where user can still copy the mails back. Also DELETEd mailboxes are moved to another namespace. See http://wiki.dovecot.org/Plugins/Lazyexpunge for more information. This is similar to Cyrus's two phase expunge:

Hi, No, I tried fetching over imapc too exactly as you suggested. In my case it was not from cyrus, but from CriticalPath. isync was finally able to do the job, preserving flags and doing UIDs mapping. The most boring part was generating proper config file for thousands of accounts. A working imapc/dsync would have been better. Emmanuel. Le 26/11/2015 15:24, Sami Ketola a ?crit : > Hi,

HI, one of my users asked me, wether smartcieve is still available after migration from cyrus to dovecot, or not. Is this possible, because smartsieve is designed for cyrus-Imapd? Or is there something similar available for maintaining the custom user rulsets by the users? ttyl, Django

Hello, is the LDA linked against the Cyrus SIEVE library or against the fork at libsieve.sourceforge.net ? It seems Cyrus SIEVE from src/libsieve/README in the lda sources. libsieve seems to be better suited for inclusion in non-cyrus software and should be completely independent from libcyrus. The README for cyrus version of libsieve also states that: "It should compile without libcyrus,

Now that I have a working kvm setup, I thought I'd finally try how Zimbra works. This is mainly some microbenchmarking, so it may not have much to do with actual performance in real life. Setup: - 1GB memory given to kvm (from host's 2GB) - Intel Core 2 6600 (kvm uses only one CPU) - CentOS 5 - 15GB qcow2 image on XFS filesystem - Zimbra 5.0 RC2 RHEL5 x86_64 - Dovecot latest hg,

I cleaned up the lib-storage code a bit so that it's easier to write support for new mailbox formats. It could still use a bit of cleaning up. Anyway, I thought I'd try how easy it would be to implement Cyrus-like mail store which would consist of only Dovecot's index files and "<uid>." message files. Flags and everything else is kept only in Dovecot's index files

I haven't been able to find anything about a port of the ogg/theora decoder to the iPhone. I'm somewhat amazed it hasn't been done, really, given the campaign against the iPhone in part for "not supporting open source codecs". So, is there an unspoken ban on this, am I searching in the wrong places or am I just the only one who'd really really like to be able to stream

Does anyone have any experience installing/configuring the latest Samba on AIX 5.2?... If so, would you care to share your notes? Thanks all. Andy Speagle "Always remember that you are unique. Just like everybody else."

I thought I'd try benchmarking with dbmail (v2.2.4) to see how much slower a SQL backend could actually be. Skip to bottom for the conclusions. Originally I ran the tests with the databases being in XFS filesystem. MySQL's performance was horrible. It went 3-7x faster with ext3. MySQL 5.0.30 backend (innodb): ./imaptest clients=1 - append=100 seed=1 secs=30 msgs=1000000 logout=0

Hi Folks, Apologies to anyone who'd prefer not to see this query on this list; but I'm asking because it is probably the forum where I'm most likely to get a good answer! I'm interested in the provenance of the name "normal distribution" (for what I'd really prefer to call the "Gaussian" distribution). According to Wikipedia, "The name "normal

Hello For those SOHO customers (ie. at most, a couple of POTS/ISDN connections and simultaneous SIP calls) who'd rather not use a big, noisy PC to run Asterisk, I'd like to offer an alternative that has the following features: - not old hardware sold on eBay, ie. it must be up-to-date hardware sold by a company currently in business - compact, silent - has room for a 2.5" hard-disk,

I am having the same trouble with automatically mounted home shares with samba 2.2.1a (PDC, domain logins, roaming profiles) and NT4WS sp6a. If I login as one user, logout, then login as another, I can view the previous users home share as well as my newly logged in users home share (lather, rinse, repeat...). The NT box has a machine account, domain logins work, profiles work, login scripts

http://dovecot.org/test/ Fixed mbox corruption in some cases where it wrote headers over beginning of message body. Fixed recent flags to work correctly with mbox. Fixed LSUB command to send LSUB replies instead of LIST replies. Then there's NTLM support from Andrey (which I hopefully didn't break) and dovecotpw utility from Joshua. And then some generic status report: For last few

Appreciations for the initiative! There are some people in the Berlin C++ user group [1] who may be interested. Also there was an active compiler meetup group [3] a few years ago. As far as I know these guys mostly joined the Strange Group Berlin [2], but may still be interested in a more compiler-focused meetup. For the people cc'd: please let us know who'd like to participate in a LLVM

Hello, We would like to do a feed back to this active mailing list. We are working on a migration project from cyrus to dovecot. And we have just completed the benchmark sequence. As I say, this benchmark is here only to show that our old imap server is out to date. I would not be the source of controversy at all, so I try to explain my approach. Because the only thing I found was this old
