[aur-general] Can not upload moinmoin package

Hi, after aur moving, I can't upload package, bigger than 100-200Kb. connection hangs after this size uploaded. I sniff conversation with wireshark and found 'TCP Acked lost segment' packet near the end. May be uploading is in progress, but very very slow. Please advise, how can I test it to find where is the problem? (ssh, cvs works quite slowly, but don't hangs)
