[AccessD] Speed Issues on network just with Access App

[Jim Dettman]

John,

<<Any other ideas? >>

 A few.

1. Anti-virus - I would assume it's the same for all, but try turning it
off.
2. NIC drivers - make sure their up to date.
3. Make sure there is no diagnostic protocol loaded for the NIC.  If so,
remove it.
4. Make sure the NIC is not set to go to sleep (low power mode)
5. Are you using mapped drives or UNC?  If mapped, default settings in Win 7
disconnect a mapped drive after 10 minutes of inactivity.  You can disable
this.
6. You should disable ipv6 if your not using it.

That's it for the moment off the top of my head.

 Oh and the MaxBuffers, set it to the max of 65535.   There was a bug in
some versions of Access when running on a 64 bit multi-core processor.   JET
has three background threads by default, one of which was for cache cleanup.
If the threads ended up on different processors, they can block one another.
Setting MaxBuffers to the max alters the cache cleanup process to work
around that.

Jim.

Not sure if any of you have had the below issues before, but I haven't in
the dozens of years of using access.  Driving me nuts, along with the
customer.  Hope someone can help.  Sorry for long post but wanted to share
details.

About 15 users w/Access 2000 running a front end access program
Backend lives on a server in a shared folder (both FE/BE are MDB's)
Gigabit Ethernet Switch
Workstations are (were) XP Pro SP3, Win7Pro SP1 64Bit
XP machines are Dell Optiplex 360's and 380's
Win7Pro machines are Dell Optiplex 3020 Small Form Factor and Micro, and one
Opti 7010

Above combo has been running fine since pretty much before dinosaurs became
extinct.  Besides Access, some users have Quickbooks, and everyone has some
flavor of Office H&B (2007, 2010, 2013, 2016).  None of the H&B come with
Access, so only one version of Access on the PC.

In attempt to get remaining users off XP, I bought more Dell's, but they
were the Optiplex 3040 Micros, Win7Pro 64Bit.  Not too long after putting
these on the network, some, but not all, of the 3040 users experienced
slowdowns where a screen that would normally take 2 seconds to open up, now
taking 10, 15 sometimes up to 2 minutes.  Not consistent, user might work
fine for a while and then bang, slow to a crawl, pretty much unusable.
Other 3040 users may or may not have same problem, but then some of the 3020
micro users experienced the same problem where they never did before, but
not nearly as many times as the 3040 users.  Very strangely, the XP users
never experience any of this nor the 7010 w/Win7Pro 64Bit, even when the
other users are.  They just move along.  So to with the Opti 7010, no issue.
And all machines are running fine with all other apps - QB, Word, Outlook,
PDF's, Internet, etc. - Just Access Issue.

Saw various articles describing same problem, even with a standalone
workstation running both FE and BE with Windows 7 64Bit.  I haven't seen the
issue if there is only one user in the system (common on a Saturday).
However, I've seen this issue with just 2 people in.

Although I can't tell if every machine needs the below or just ones with
issues, I have tried the following based on many posts that I have read:

PC Specific:
Group Policy Change to Turn Off Multicast Name Resolution=Enabled
Registry MaxBufferSize=50,000
Turn Autotuning Off (NetSh Interface TCP Set Global Autotuning=Disabled)

Non-PC Specific
I replaced the network switch with an older gigabit model but again, I do
not think is it.
Replaced wiring at some workstations
Made sure the Lock file was deleted in the shared folder when all users out
so it would get created fresh
Access 2k SP1 or SP3 was installed on workstations
Checked Tools/References to make sure none were missing on the workstation
VBE6.DLL was dated 3/17/2015 on the Win7 Machines
Bought a used Opti 7010 with same specs (because only other 7010 has never
had an issue to date), set it up and put it on the network.  Issue right
away with only one other person on the network
Probably a few other things I forgot to mention, I've lost track

Customer has brought back some old XP machines because of issue and they are
working just fine.

I have a 32bit Win7Pro machine that I am almost done reformatting and will
put on the network to see if that does anything.

Any other ideas?  I don't think the number of users is the issue.  I have a
2002 Insurance app with 65 people in it from three locations all day long
and no speed issues.

Thanks for taking the time.

John
