Default load average from nexus

Hi there,

i have a little problem with the nxserver/client. We are using nxserver 1.08
(adapted from Hannes for tcp/.net transport) and a programm written in
vb.net for syncing tables to an access or mysql database. The client is now
in betastadium but i have troubles with the connection speed.

I can syncronise tables with 4 columns and 64000 records in 5 minutes. The
nxfilesize is 12mb. When i will syncronise a table with 500000 records and
21 columns the the nxserver takes 100% cpu speed for more than 90 minutes
before the syncronisation begin. We have enough RAM in the machine (more
than 2GB!).

Have anyone any idea for this problem?


Many thanks

That's defintely NOT how it should work. Any chance to get hold of the data
and a piece of code to reproduce?

Hi Hannes,

that's not the problem. When I zip the db (54mb) and upload to a ftp-server
where you can download it, is this ok?

Hi Hannes,

sorry for my late answer, but i solved this issue today. In the past I
tested this with your nxserver v1.08 with the "Direct TCP/.NET Transport".
Today I have downloaded the nxserver v2.06 from the nexus Homepage. I run
the server and configured it. Now the load average is 2-3 minutes by 90% cpu
usage for the 300mb table, then the select works fine.

Is the nxserver2 from the webside a time trial or can i use this?

Many thanks and greetings from Austria.

I assume you downloaded from here:
http://www.nexusdb.com/showpage.asp?Id=68

If that's the case these are full versions without expiry.

Hi Hannes,

That's right. The v2.061 works fine and the replication with the database
and mysql works great. The time is shrink to 2 hours for 5.000.000 records
over 6 tables.
The cpu load is more than 80% increased for the queries. There are many
arguments to use this.

Many thanks and greetings from Austria
