Network Speed and IT Guys

Hi All,

What is the best tool or way to show the IT guy(s) that the network speed is the cause of the problems for TopSpeed files?

Any suggestions please?

Hi @Marius_Nel

I’m not sure, with the information you have given, that there is enough information for anyone here to be able to advise you or the “IT guy” on whatever issues are being seen.

So it might be best if you could provide answers to the following:

  • Can you describe the issue more
  • Do you have more than one client and it’s only one specific client experiencing the problem
  • What hardware and operating systems are involved
  • Op Locks turned on/off
  • Corruptions

Hopefully with extra information someone may be able to help more.

I deal with this all the time and it can be a struggle since 1) what is Clarion/Topspeed 2) oh it’s not using SQL 3) ISAM WTF??? I get this all the time. I usually use Process Monitor to show them all the file open\close and I/O and eventually they see the lag times. Good Luck. Be sure to let us all know how you did with this “battle”



This one client complains about speed and the client is at the end of the discussions with the IT guy. SO I need to proof to him/IT Company that it is something with his network setup and not the system as he likes to points out to the client the whole time. (One of hundreds of other clients that works 100%)

The client complains that if they are more than one user using the system it is to slow to use, but if they log in on the one back office and use the system it works 100%. (The same system and or network)

Server is a windows 11 pro PC with SSD drive
Will check the Op Locks but I asked if that was off and they replied yes.
A lot of data corruptions lately.
Wired network running at 1GB

I need a tool or way to show them it is their settings and not the system.

Thank you Kevin, will give it a go.

we are running Windows 2019 servers and everyone logs in via RDP and access TPS files on different servers and we run reports and import\exports all day long. We have up to 100+ users active running different programs accessing files w/o slowness.

That’s usually a symptom of oplocks, which allow client cacheing of data to speed things up. with 2+ stations oplocks are nullified. So that’s why 1 is fast (client cache) and 2 run at normal speed (no client cache)

Problem with oplocks is you can only turn it off if using SMB1, which in latter versions of windows not active, so it’s a bit of a problem. It can be done, it’s just painful.

You might try giving more time to background processes on the server system, thats a system control panel setting.
Other than that I’m not sure what can be done, other than go to ipserver or sql

i can only say I never managed to make app residing on the windows server share and using tps as db run well with multiple users running the same app at the same time.
Very simple ones - yes, but with just a bit more records, unfortunately not.

That was one of the reasons I moved to SQL. And.I still have some that need the conversion to SQL.


My advice - definitely use the IP Driver. It will improve speed on even the crappiest network - including wifi. And you won’t see any more TPS corruptions either. But Oplocks must be turned off. It also helps explaining to MS-indoctrinated IT support guys when you mention the magic words Client/Server, data packets etc…

This fight started for me in 1986 when ArcNet and Token Ring were the kings. I have found choking is often effective. I have found that once you have proven your point multiple times over, it is your only option. And, it never ceases to amaze me that each generation (training, not age) of Infrastructure guys revert to the same arguments… Oh, well, what are you going to do???

Fast, short-term solution is to get an RDP server in there.
I have done both IP Driver and RDP. For short-term gains, I’d go with RDP.
Going the IP Driver route could potentially involve a lot more work and a whole lot of testing under multi-user conditions. I had to deal with file error #27 with just one user under IP driver and I had to workaround program lockups with multiple users.

In my previous job, I was the network guy and the app used TPS files. I never was successful in preventing TPS corruption. I tired a lot of different things. Speed was never a complaint. The app was always run in a RDP session and run locally on that server. I switched to SQL Server and never looked back. Never had speed or corruptions with SQL Server. All my work now used SQL Server. Also allows for multiple app platforms accessing the same databases. I have PHP (both backend and web) and Clarion apps accessing the same database. Works great.

BTW: I never had TPS corruption when the apps ran on a Novell Network. :slight_smile:


Same reasons & results in long ago moving to PostgeSQL. The ease of creating aggregate functions/subqueries for summary data is reason enough, but many other advantages as well.

Fast, short-term solution is to get an RDP server in there.

I ran it on a RDP server and still had corruptions. When users left the app open and session closed or then they suspended a session and not close. Lot of UE errors can happen. I left the same RDP server in place and switched to SQL and corruptions/database errors went away.

RSchofield, do you happen to know if STREAM( ) command was used throughout the code in the app or if the .TPS files were being stored on a different server than the RDP server or on a NAS? I can imagine that either case could trigger problems. Otherwise, I just find it hard to believe that there were corruptions when running under RDP with the .TPS files on a drive within the RDP server. Although, I can think of a case where live backup software can cause a problem with a file system like .TPS where the files are constantly opened and closed and the backup software tries to squeeze in a back.

To measure the network speed, I use the free version of “LAN Speed Test” because the supposedly 1Gbps LAN usually runs at 100Mbps because of bad cable connections, sloppy LAN card setup, etc. It helps with the performance of Microsoft Access data files, so I’m sure you will get some useful data for TPS files too.

“You can’t solve a problem until you can measure it.”

Also, check out the oplocks settings and other advice offered above.

Word of warning: getting the IT guys to actually run LAN Speed Test may be a problem, because they don’t like having to fix their own setup problems.

No STREAM and app and TPS in same folder. No live backups either. I tried many things to try and fix the problem, but never did. Windows isn’t designed for ISAM files. Netware was great. The same app running on NetWare never corrupted the TPS file, Windows always did.

Hi All,

Thank you all for the feedback. I will use these to reply to the client and IT. Let’s see what they say and if they can get it sorted.

I really appreciate all your feedback.
