Network ftp speed
Background;
FTP-ing a small 210K file to a HP7410 attached to a EVA500 the averaging speed 400KB/s
FTP-ing a small 210K file to a K570 the average speed is 4500KB/s
FTP-ing a 31MB file to a HP7410 attached to a EVA 5000 the average speed is 5500KB/s
FTP-ing a 31MB file to a K570 the average speed is 4800KB/s

Any hints? Both servers are on a CAT 5000 switch (same blade). There is no bottlenecks on the switch confirmed by a Cisco professional.

Hi,

They all have the same HP/UX release ? Same patch level ?

With lanadmin check duplex settings ( -x argument ) ... if necessary, force full duplex ( -X setting )...

Good luck !

I'd look at the port configuration on each CAT as well.

Cheers,

Hi,

the ftp performance can differ from file/filesystem to file/filesystem. The ftp client is reading the file with a buffersize of X kbyte, and the server is writing it.

Using a bigger buffersize increase the speed for bigger files for example. If it's possible, play a little bit with the buffersize.

The options are FILEBUF and NETBUF I think.

Regards
Malcom
