I tested GT.M over network and I experienced 20
times(!) slower performance than results of a one host
The test code:
FOR I=1:1:1000 FOR J=1:1:100 FOR K=1:1:10 SET
I used 33280 byte block size, 32767 byte record,
journaling. I used one remote server (gtcm_gnp_server).
The Global Directory was configured with the same
parameters in both machine (except the file name, of
2,4 GHz P4
512 MB RAM
1 GBit Intel NIC
Dual 2,8 Xeon
4 GB RAM
1 GBit NIC
36 GB U320 SCSI
(I made this test on another client with same
configuration, but the performance was dismally.)
The CPU utilization was low (about 6-15%), the network
utilization was low also (about 4Mbit).
Do you have any suggestion how can I inrease the
Thanks in advance,
