Large Commit Issues! 10Mbps Upload cap on a Gigabit LAN
Hi, I'm running into an issue that nobody seems to know a heck of a lot
about. I'm moving a whole bunch of files from an old repository system
(RCS) to SVN (i.e 80,000+ files, ~60GB). However, checking in is virtually
impossible. I have a Gigabit connection to the server and all other data
transfers are blazing fast except for SVN which caps at 10Mbps uploading to
the server and 20Mbps when I'm checking out. I would really, really
appreciate any help on this subject as I have googled this for hours to no
avail.
Thanks,
Ahmed

we have no problems with large commits whether they are large by bytes
or by number of files.
i think people will respond if you specify your system configuration (OS
version, Subversion version, Subversion backend)

thanks for details.
a) defrag ur client's disk drive.
b) test 'export' and compare its performance agaisnt 'checkout' for same Repo Path. This is due to significant overhead invovled on checkout in order to create woring copies containing pristine copies of checed out files. Hence CO is always lot slower thn ur raw copy tests.
c) consider setting "compression off" (zlib) both on ur SVN client & SVN server (mod_dav_svn). U have good bandwidth available, so IMO compression is an unwarranted overhead on either ends.
d) confirm that network cards on both server & client side have checksum offloading enabled. (i would assume that to be the case as default Win2k3 install)
e) what is access method for SVN Client .. assuming https?
(a), (c), and (d) are applicable for 'Commit' operations as well. Similarly, pls report speed of 'import' a large file into the repo.
50% peak utilization on server some how hints about a bottleneck in the chain (unless its dual proc / HT, and one of the CPU is peaked at 100%).. but lets leave that aside for the time being. BTW, how much RAM in the server?
cheers

Hi Shirish,
Below are the system specs and some further testing that I did. I'm still trying to figure out the bottlenecking issues. Let me know if you see anything that I missed.
Regards,
Ahmed
Server:
2.4 Ghz Intel Xeon with 533Mhz FSB
512 L2 Cache
Using RAID 1 & SCSI drives capable of 160MB/s
There are no IRQ duplicates (i.e. no conflicts)
It has 2, 1Gbps Network cards
Running Win'03 Server (up to date on all service packs/patches)
Client:
Intel P4 3.0Ghz
1GB of Ram
1Gbps Network card
I just copied a 2GB file from the server to the client and vice versa. The transfer was very fast and used ~300Mbps (Average), both ways were about the same. I'm using Net meter on both ends to monitor the bandwidth usage, and until the file transfer the bandwidth monitor was pretty much showing little activity so I assume 99.9% of the bandwaidth useage was due to the file copy operation between the server to the client hard drive and then back again. I checked to make sure that all irritating background processes like Norton, were shut off and all the microsoft fast indexing services were shut off. There is virtually no server load besides the programs/transerfs that I am running, as this server is a dedicated server being used by me.
Next, I just tried doing a checkout of a 1.8GB file and looking at the bandwidth monitor, it looks like the maximum bandwidth usage was 28Mbps and average was ~20Mbps. During the transfer, neither the client or server were really pressed for resources, as the server used a max of 50% of it's processing power and ~281MBs of memory, the client pc shows similiar load.
Please let me know if this info helps. I am still left wondering... Thanks again for the help.

Ahmed

Hi Samay,
Thanks, I'll check these things out tommorrow and get back to you. The
way I compared it was be doing a simple file copy operation (to and from the
server). I copied 30GB of data from the server to my PC.
The Server has a SCSI Hard drive and my PC has serial ATA. I'll let you
know the config and hopefully you'll find something I missed (I really hope
so, it would make my day!) . I just want
to be able to prove that it is not an SVN issue but rather a limitation of
the machines. Thanks again, and I'll be sending the details tommorow.

Ahmed

specifically for the client (if applicable thn server too) .. look 4 and disable following
a) anti-virus (or exclude SVN working copies)
b) desktop search tools -- e.g. GDS, MSNSearch etc.
c) Any indexing service (MS Indexing)
yeah, perfmon will be a way to look as u state its a Win32 client/server.
without actual confirg details, its difficult to help, for you say you have already looked at everything!

Thanks for getting back to me. But I've looked at every other possible
bottle neck. Anyother transfer from the server to client is blazing fast
(at least 450+Mbps). I had it down to just the PC & server talking, and
there is no way I could get a checkout done where more than 20Mbps bandwidth
use (I was checking the bandwidth usage as soon as I did a checkout or
checkin). I'm pretty sure it's subversion itself, doing some sort of memory
stuff, where a buffer size is set or something... Both my PC & Server are
running on Window (PC: XP SP2 Server: Win'03). It's just wierd! It takes
me a long time (>50mins) to do a ~5-10GB checkin/checkout. That's just
waaay too slow when I have nearly a TerraByte worth of data that I need to
put under version control. I read some other people were having similar
issues with checkin/checkout of large files, I mean 10-20Mbps is great, just
not so great on where you have a 1Gb connection with no bottlenecks. Once
again, thanks for any input on this matter. I am a passionate advocate for
open-source software, and if I would love to put show off a subversion

Transfer speed also depends on
a) server specs -> processor, memory
b) bus speed
c) any IRQ sharing (e.g. Eth0 & Drive Controller sharing same IRQ-- ouch!!)
d) speed of drives & raid controller, raid config
e) server load (processes in wait stage?)
f) operating system & configuration.
g) and MTU (jumbo frames?) on the network itself
of course least common denominator of the server & cliebt capability defines the over all speed u may get. Care to share details above?

Hi, I'm running into an issue that nobody seems to know a heck of a lot about. I'm moving a whole bunch of files from an old repository system (RCS) to SVN (i.e 80,000+ files, ~60GB). However, checking in is virtually impossible. I have a Gigabit connection to the server and all other data transfers are blazing fast except for SVN which caps at 10Mbps uploading to the server and 20Mbps when I'm checking out. I would really, really appreciate any help on this subject as I have googled this for hours to no avail.
Thanks,
Ahmed
