Default torrent clients are driving me nuts

I give up using rtorrent any more, untill they fix bug, that couses FreeBSD (and as i found in this forum, OpenBSD as well) to lag.
It pisses me off

So I went searching for new clients.

Here's what i have tried:
rtorrent - well, just to point out. It's good but has serious lags.
ctorrent - I like it, i think i might write script that starts it automatically, and it could be usable (i would prefer single process, but i can live with it)
transmittion_gtk - it looks good, it has good features, BUT it's downloading speed is low. it's being outrun by r/ctorrent
transmittion_cli - i absolutely didn't like it
btpd - i could start daemon, but didn't manage to connect to it with dtcli.

I didn't try
* deluge, because i'm minimalist, and i don't like mixing python with apps.
* any java torrect client. And i doubt you can talk me in to try one.
* any torrents for kde, to many dependencies
* qtorrent, because i remember how disappointed i was 2 years ago when i tried it
* unworkable, because of how it sounds
* others


can anyone suggest anything good.
i prefer console based clients like rtorrent

Makes FreeBSD lag how? Network congestion? CPU/memory hog?
I've been using rtorrent for a few years, I never encountered such behaviour.

What do you mean by that? That doesn't seem to make much sense.

Everytime i download torrents at high speed, mouse pointer is twitching (big time), music is twitching.
i'm not sure at what exactly speed it starts, but i know for sure 6000Ks (rtorrent total download speed) download will cause it, not to mention that downloading torrents from local tracker i can get up to 13000+Ks
I doubt it's HDD's fault. because i'm writing to SATA150, which almost ain't used by anything else.

basically downloading torrents with high speed makes system almost unusable.
That's why i was limiting download/upload speed to 2200Ks total

Also CPU usage is pretty extreme (i think)

- i don't want to install 10 more dependencies, most of which are python. It's in my head, that i don't want to use apps, that relies on python. (can't explain it.... my bogus mind), but if you can convince deluge is good, i might hive it a shoot, however i'm starting to like ctorrent

I'm using transmission_gtk, and I don't have any problems with it.

I like transmission - it's simple, fast and works fine for me. Also at high speed of download I don't have any problems with CPU usage.

I don't like too Java-based torrent clients, and KDE dependent too.

well, it might be me.... but i think rtorrent downloaded file way faster than transmission_gtk for me.
I will check again.

OK, i checked.
Ctorrent was downloading same files, at same time 3 to 10 times faster.
On same computer (i ran them in parallel, independent)

Comparing the speed of a torrent client is a bit strange.. the technology itself is dependent on the capabilities of the seeds and peers.

I for example, tested the btpd client.. and I can achieve maximum throughput with it.. though, not on every torrent obviously.

If you're experiencing speed issues, perhaps you configured the client improperly?

WINE + uTorrent. Doesn't get much nicer, faster, or slicker than that.

However, then you'd also have to install a Windows version of a web browser, in order to have "click link and start torrent download" working correctly.

Regarding rtorrent problems:

I never encountered any problems, can you post your ~/.rtorrent.rc? There are some options you can tweak which can significantly improve performance.

Also, I never encountered problems with CPU usage, I run rtorrent on a PIII 800/384MB RAM so I definitly would have noticed any.

.rtorrent.rc
Code:
# This is an example resource file for rTorrent. Copy to

# uncomment the options you wish to enable.

# Maximum and minimum number of peers to connect to per torrent.

# Same as above but for seeding completed torrents (-1 = same as downloading)
#min_peers_seed = 10
#max_peers_seed = 50

# Maximum number of simultanious uploads per torrent.
#max_uploads = 15

# Global upload and download rate in KiB. "0" for unlimited.
download_rate = 2000
upload_rate = 200

# Default directory to save the downloaded torrents.
directory = /home/Files/tr/f

# Default session directory. Make sure you don't run multiple instance
# of rtorrent using the same session directory. Perhaps using a
# relative path?
session = /home/Files/tr/.session

# Watch a directory for new torrents, and stop those that have been
# deleted.
schedule = watch_directory,5,5,load_start=/home/Files/tr/*.torrent
schedule = untied_directory,5,5,stop_untied=/home/Files/tr

# Close torrents when diskspace is low.
schedule = low_diskspace,5,60,close_low_diskspace=8000M

# Stop torrents when reaching upload ratio in percent,
# when also reaching total upload in bytes, or when

# example: stop at ratio 2.0 with at least 200 MB uploaded, or else ratio 20.0

# The ip address reported to the tracker.
#ip = 46.88.15.155
#ip = getlost.fc

# The ip address the listening socket and outgoing connections is
# bound to.
#bind = 127.0.0.1
#bind = rakshasa.no

# Port range to use for listening.
port_range = 6890-6999

# Start opening ports at a random position within the port range.
port_random = yes

# Check hash for finished torrents. Might be usefull until the bug is

#check_hash = no

# Hash read-ahead controls how many MB to request the kernel to read

#hash_read_ahead = 10

# Interval between attempts to check the hash, in milliseconds.
#hash_interval = 100

# Number of attempts to check the hash while using the mincore status,
# before forcing. Overworked systems might need lower values to get a
# decent hash checking rate.
#hash_max_tries = 10
also, i have another idea.
I was messing with sysctl flags (basically i was fallowing book FreeBSD 6 Unleashed by Brian Tiemann)

sysctl.conf
Code:
security.bsd.see_other_uids=0

kern.coredump=0

net.inet.tcp.delayed_ack=0
kern.ipc.maxsockbuf=2097152
kern.ipc.somaxconn=512
kern.maxfiles=65536
kern.maxfilesperproc=32768

net.inet.tcp.sendspace=65535
net.inet.tcp.recvspace=65535
net.inet.udp.recvspace=65535
net.inet.udp.maxdgram=57344
net.local.stream.recvspace=65535
net.local.stream.sendspace=65535
kern.ipc.nmbclusters=65535

vfs.usermount=1

net.inet.tcp.blackhole=2
net.inet.udp.blackhole=1
net.inet.ip.random_id=1
do you think these could cause problems at current state?

net.inet.tcp.delayed_ack: Delay ACK to try and piggyback it onto a data packet
kern.ipc.maxsockbuf: Maximum socket buffer size
kern.ipc.somaxconn: Maximum pending socket connection queue size
kern.maxfiles: Maximum number of files
kern.maxfilesperproc: Maximum files allowed open per process
net.inet.tcp.sendspace: Maximum outgoing TCP datagram size
net.inet.tcp.recvspace: Maximum incoming TCP datagram size
net.inet.udp.recvspace: Maximum space for incoming UDP datagrams
net.inet.udp.maxdgram: Maximum outgoing UDP datagram size
net.local.stream.recvspace:
net.local.stream.sendspace:
kern.ipc.nmbclusters:
Maximum number of mbuf clusters allowed


I will disable and reboot, to see what happens
However i doubt it's the reason, because ctorrent was downloading torrents like mad (total 10.1M/s [average speed in last 20s, so they say]), and cpu load was low, and BSD didn't lag.


EDIT, didn't yet do it.
added
Code:
hash_read_ahead = 8
hash_max_tries = 5
hash_interval = 10
to .rtorrent.rc

and checked again.
1st time FBSD lagged was when rtorrent reached 3.2M/s (it was 300M file, so it cound't get to full speed)
then i restarted, and next time it was at about 4M/s
at 6M/s Wcpu was 34%, cpu state: 19.2 user, 29.2% system, 20.7 interrupt (on smp maching. P4-HTT @3GHz)

I have 2G ram and 1G swap, swap wasn't used

I disabled settings that i marked red in sysctl.conf.
Seams lags decreased a lot.
only had 5 lags @5+M/s in period of about 3minutes.
This is defiantly better, that it used to be.

I still have lags, but way less and shorter.
I'll keep monitoring.
i want to see what will happen at 8 to 9M/s


EDIT:
ctorrent sill seam to be better at some point

No that i don't want.
I don't want operas torrent client, because last i used it it sucked greatly (sorry if i'm rude, but there is no other word describing my experience)

besides, i don't think i want to use opera because it's closed source. + i have to compile qt3


thanks for reply

What's wrong with a python based bittorrent client? The original bittorrent client was even coded in python.

EDIT: btw Deluge is my favorite client right now, it has a similar feel to utorrent. you should try it, its nice

I really like ktorrent. It does have KDE as a dependency, but it has always Just Worked for me, and the UI is intuitive and easy to use. The learning curve is low. It may be worth just installing KDE's libs and stuff to use ktorrent because of how well it works.
