Has anyone used the AudioCodes MP-20x? http://audiocodes.com/Objects/Analog_Telephone_Adapter_Series_MP_20X.pdf Seems like a good device, but I can't seem to find anyone actually using them... -------------- next part -------------- An HTML attachment was scrubbed...

I just replaced my drives for Dovecot using Maildir format with a pair of Solid State Drives (SSD) in a raid 0 configuration. It's really really fast. Kind of expensive but it's like getting 20x the speed for 20x the price. I think the big gain is in the 0 seek time. Here's what I bought.

...it down to two lines of code in nmbd_winsserver.c. in function initiate_wins_processing ... if(wins_server_subnet->namelist_changed) wins_write_database(); ... My first hack worked. I commented them out. Processing time went down to >1% and responce time probably went up by at least 20X. Browsing works better than I have ever expected. Before I did this I had tried everything, 1.9.18p10, linux boxes as lbm's, and 2.0alpha. If you have more than 100 clients this is a must have!!! I'm not a developer, but these changes MUST be re-integrated into the code. This will fix...

Hi, We are considering using a ZFS based storage as a staging disk for Networker. We''re aiming at providing enough storage to be able to keep 3 months worth of backups on disk, before it''s moved to tape. To provide storage for 3 months of backups, we want to utilize the dedup functionality in ZFS. I''ve searched around for these topics and found no success stories,

[originally reported for ZFS on FreeBSD but Pawel Jakub Dawid says this problem also exists on Solaris hence this email.] Summary: on ZFS, overhead for reading a hole seems far worse than actual reading from a disk. Small buffers are used to make this overhead more visible. I ran the following script on both ZFS and UF2 filesystems. [Note that on FreeBSD cat uses a 4k buffer and md5 uses a 1k

Compile times increased by roughly 20X after upgrading the Radian compiler project from LLVM 3.1 to 3.3. I am curious whether this is considered normal. If it is not, I would appreciate some help figuring out what it is about the Radian compiler's output which is causing LLVM to spend so much time compiling such small programs....

...just to verify the obvious: these are both the same type of build (Release-Asserts, or whatever) rather than an optimized 3.1 vs a 3.3 debug build? (I know this is unlikely, but I've managed to mix-up my configurations in the past so it is worth checking before trying more involved options). A 20x slow-down that looks to be on everything (rather than one component) is a strong symptom for this.

...taking 4-5 times as long than with it disabled.) Write speed seems to be fine. Testing is showing ~95 MB/s, which seems pretty decent considering there''s been no real network tuning done. The NFS server we''re testing is a Sun x4500, configured with a storage pool consisting of 20x 2-disk mirrors, using separate SSD for logging. It''s running the latest version of Nexenta Core. (We''ve also got a second x4500 in with a raidZ2 config, running OpenSolaris proper, showing the same issues with reads.) We''re using NFS v4 via TCP, serving various Linux c...

Did you mislead me Timo? You said search in 1.1+ is faster than 1.0. I'm seeing approximately 20x *slower* search times in 1.2.10. Via Thunderbird, a full body search of my 11,000+ message IMAP folder hosted by 1.0.15 used to take less than 10 seconds. Since upgrading to 1.2.10 the search is taking over 3 minutes, the imap process servicing the client pegging one CPU at 100% for the duration...

Recently upgraded our gems to the most recent beta gems, and found that our app runs about 10-20x slower. Db requests are still fast, but there was a noticeable lag between each step in the process to render a page (when tailing the log). Reverting back to our previous set of gems (0.14.2.2825) resolved the issue. Is anyone aware of the cause? Any guesses? I''m happy to help debug,...

...attr<- were primitives, and hence would modify in place. Re-running with gctorture(TRUE) yields roughly similar numbers, although there is no memory release because gc is called earlier, and the assignment of allocations to line is probably more accurate given that gctorture runs the code about 20x slower: file line alloc release 25 read-table.r 221 0.387299 0.00e+00 26 read-table.r 222 0.362964 0.00e+00 The whole object, when loaded, is ~4 meg, so those allocations represent fairly sizeable chunks of the total. Any suggestions would be greatly appreciated. Thanks! Hadle...

I have looked at problem with Fermi GPUs where changing to higher clock led to really bad perfomance (with GpuTest 20x worse perfomance) and later also crashes of the nouveau. It seemed to be affected by Shader Clock in Voltage Entries in the video BIOS. Disabling BYPASS_PLL_CHECK in CLK0_CTRL seems to completely fix the issue. I have tried to search this BYPASS_PLL_CHECK in Nvidia traces but seemed it wasn't u...

Hi guys, I was wondering whether there's anyone who could share his/her experiences with using Microsoft RTC Library. In particular I am wondering what Ethernet capacity should I have in scenario of 30 people using Microsoft RTC Library for SIP communication (PBX is obviously Asterisk :-) ) concurrently (alaw codec being used)? What problems can be expected in such scenario? Would a good 1

...lgebra'-heavy things with R, I had compiled R 2.9.0 against the ACML blas. ACML contains lapack, so I killed two birds with one stone. Generally, I would do a configure with ./configure --with-tcltk --with-blas="-L/opt/acml4.3.0/gfortran64/lib -lacml" Worked perfectly. Led to 10-20x speedup in certain calculations. Things haven't been so good since moving to CentOS. The install of the OS went fine, but I can't for the life of me figure out how to compile R against blas - ACML-variety or otherwise. Moreover, putting in --with-lapack explicitly causes all sorts of e...

I am trying to sample a subset from a matrix using sample. The size of the matrix is 20X 1532. It works fine with this, but when I transpose the matrix and try to sample it, it returns null. pick.set<-sample(tissue.exp.t,5,replace=FALSE,prob=NULL) Is there something that I am missing here ? Thanks ../Murli

...y, libjit is a win here: > a rebuild and relink of my libjit-based code takes under a minute. > I think it takes 20 minutes or more to link my LLVM-based JIT on my > laptop. Are you using a debug or a release build? A release build (built with make ENABLE_OPTIMIZED=1) is often 10x to 20x smaller than a debug build, and links correspondingly faster. On some machines, a release build builds *faster* than a debug build because the debug symbols are so huge. The only thing you lose with a release build is the ability to step into LLVM libraries in a debugger. > * Likewise, lib...

Hi, I am using IPFW on FreeBSD 4.11 I am facing two problems: - SSH sessions timeout after a while - When I run "/sbin/ipfw -q -f flush" in the rules script all connection get reset (and I am thrown out of the box). Is this standard functioning of ipfw or do I need to change any configuration? Thanks, Siddhartha

...tation. This gives us much better register allocation (function-wide instead of local), possible compiler optimizations (static analysis can prove that some accesses always read initialized memory), and a fast start-up. Our preliminary measurements show 3x-4x slowdown; compare it to Memchecks's 20x and DrMemory's 10x. (See http://groups.csail.mit.edu/commit/papers/2011/bruening-cgo11-drmemory.pdf for those numbers). But this brings the major issue as well: msan needs to see all program events, including system calls and reads/writes in system libraries, so we either need to compile *every...
