Slow table open |
Tue, Sep 16 2008 12:01 PM | Permanent Link |
I have to main apps running dbisam and deployed in many customers.
App A, dbisam 4.24 b1, Delphi 6. Opens +100 files in startup, two databases opened App B, dbisam 4.26 b3, Delphi 2007. Opens +50 files in startup, two databases opened In both cases, a scenario is +/-: file server, shared folder in a server (w2k svr, 2003 svr or a simple XP box) clients: XP, w2k. LAN: GBit in mostly cases All XP SP1, W2K clients open App A in less than 10 seconds, App B < 5 seconds. That's good. SOME XP SP2/3 clients open App A +60 secods, when FIRST client opens tables. Second client and others open tables in a good time. App B runs the same, proportionally. The key issue is: is someone has tables opened (same server or another client or just dbsys) all machines open tables in a fast way. But first client is very slow. Also occurs closing tables. The fact is not all XP SP2/3 clients are slow. I have not idea of what combination of factors can make this. Customers start one PC at morning the first and don't care about problem, but is very strange, not? Tiago Ameller tiago put_an-a-_in_a_circle sistemasc.net Sistema, S.C. | |

Roy,
>Nah - its just Windows buffering. Ok, but not all XP SP2/3 clients are doing it. And not all servers. Do you know what registry entry is the key? Searching this topic on the Web has no significant results ... Tiago Ameller tiago put_an-a-_in_a_circle sistemasc.net Sistema, S.C. | |

<< The fact is not all XP SP2/3 clients are slow. I have not idea of what combination of factors can make this. >> Most likely this is simply an issue with the SMB file-sharing protocol in Windows. A simple way to test this is to set up the same configuration with the ElevateDB Server and test it. -- Tim Young Elevate Software www.elevatesoft.com |
