Solved: Very slow speed on SSD |VMware Communities (via “Building a lab with ESXI and Vagrant – DarthSidious”)

Posted by jpluimers on 2021/05/11

Via [WayBack] Building a lab with ESXI and Vagrant – DarthSidious while researching the possibility of running Vagrant (software) – Wikipedia on VMware ESXi – Wikipedia for building and distributing development environments:

[WayBack] Solved: Very slow speed on SSD |VMware Communities “solution” that seems to work for ESXi 6.5 and 6.7:

ESXi 6.5 includes a new native driver (vmw_ahci) for SATA AHCI controllers, but that introduces performance problems with a lot of controllers and/or disks.

Try to disable the native driver and revert to the older sata-ahci driver by running

esxcli system module set --enabled=false --module=vmw_ahci

in an ESXi shell.

Reboot the host to make the change effective.

which solves it for some who now get much faster results:

Your suggestion worked for me, now i am getting avg speed 250Mbps from SATA III SSD .

Hope will get the full I/Ops from SSD.

However:

One issue I still have is that my 4 port Syba PCIe controller card now vanishes after disabling vmw_ahci and I am restricted to using the SATA ports on the motherboard.

and you need backups:

WARNING: Doing this at least for me erases all the VMs on the aforementioned drive. Migrate as needed.

There was no response for a more permanent fix:

What is the permanent fix for this issue, should we expect a corrected native driver from VMware, or will this require a firmware upgrade on the part of the drive vendors?

and there seem to be other bottle-necks:

tried the command on a 6.7.

Deploying an OVA and I am getting 22.82….

I have a Samsung 860 EVO mSATA 1Tb SSD.

i re-enabled it, I got max 11.81.

Kind of crappy either way. Not SSD speeds IMO.

Gasexplosie en grote brand aan Westestraat in Sassenheim

Posted by jpluimers on 2021/05/11

De buurt was tot laat afgesloten (veiligheid, onderzoek, genoeg redenen), dus voor nachtopvang van mijn verstandelijk beperkte broer moeten zorgen omdat Wlz zorginstelling geen crisiszorg kon leveren en op WSW werk geen leidinggevende beschikbaar was om zorg af te stemmen.

Voor mijn off-line geheugen (bijna allemaal via [Archive.is] #sassenheim hashtag on Twitter):

Chrome supported extension IDs

Posted by jpluimers on 2021/05/11

I wonder how you can programmatically open a Hangouts link from Chrome?

These dit not help:

So did some more digging.

TL;DR: did not find a solution; so any help is appreciated.

I found the IDs of then in [WayBack] extensions/common/constants.cc – chromium/src.git – Git at Google

namespace extension_misc {
const char kPdfExtensionId[] = "mhjfbmdgcfjbbpaeojofohoefgiehjai";
const char kQuickOfficeComponentExtensionId[] =
    "bpmcpldpdmajfigpchkicefoigmkfalc";
const char kQuickOfficeInternalExtensionId[] =
    "ehibbfinohgbchlgdbfpikodjaojhccn";
const char kQuickOfficeExtensionId[] = "gbkeegbaiigmenfmjfclcdgdpimamgkj";
const char kMimeHandlerPrivateTestExtensionId[] =
    "oickdpebdnfbgkcaoklfcdhjniefkcji";
const char kProdHangoutsExtensionId[] = "nckgahadagoaajjgafhacjanaoiihapd";
const char* const kHangoutsExtensionIds[6] = {
    kProdHangoutsExtensionId,
    "ljclpkphhpbpinifbeabbhlfddcpfdde",  // Debug.
    "ppleadejekpmccmnpjdimmlfljlkdfej",  // Alpha.
    "eggnbpckecmjlblplehfpjjdhhidfdoj",  // Beta.
    "jfjjdfefebklmdbmenmlehlopoocnoeh",  // Packaged App Debug.
    "knipolnnllmklapflnccelgolnpehhpl"   // Packaged App Prod.
    // Keep in sync with _api_features.json and _manifest_features.json.
};
// Error returned when scripting of a page is denied due to enterprise policy.
const char kPolicyBlockedScripting[] =
    "This page cannot be scripted due to an ExtensionsSettings policy.";
}  // namespace extension_misc

The odd thing is that the source does not match the Chrome web store designation:

Hangouts ExtensionId Source name Web store name
nckgahadagoaajjgafhacjanaoiihapd kProdHangoutsExtensionId Google Hangouts
ljclpkphhpbpinifbeabbhlfddcpfdde Debug Google Hangouts (Extension, Beta); GOOGLE CONFIDENTIAL – FOR INTERNAL USE ONLY
ppleadejekpmccmnpjdimmlfljlkdfej Alpha Google Hangouts (Extension, Debug)
eggnbpckecmjlblplehfpjjdhhidfdoj Beta Google Hangouts (Extension, Alpha)
jfjjdfefebklmdbmenmlehlopoocnoeh Packaged App Debug 404 error
knipolnnllmklapflnccelgolnpehhpl Packaged App Prod Google Hangouts; Hangouts Chrome App is deprecated. Please switch to the Hangouts Chrome Extension.

You can not start the extensions in a tab; they need to start their view through the extension.

So these links do not work:

  • chrome-extension://nckgahadagoaajjgafhacjanaoiihapd/mainapp.html?uv_main_window
  • chrome-extension://ljclpkphhpbpinifbeabbhlfddcpfdde/mainapp.html?uv_main_window
  • chrome-extension://ppleadejekpmccmnpjdimmlfljlkdfej/mainapp.html?uv_main_window
  • chrome-extension://eggnbpckecmjlblplehfpjjdhhidfdoj/mainapp.html?uv_main_window
  • chrome-extension://jfjjdfefebklmdbmenmlehlopoocnoeh/mainapp.html?uv_main_window
  • chrome-extension://knipolnnllmklapflnccelgolnpehhpl/mainapp.html?uv_main_window

file – String format procedure similar to writeln – Stack Overflow

Posted by jpluimers on 2021/05/11

Cool Format feature from [WayBack] file – String format procedure similar to writeln – Stack Overflow:

The cool thing about using Format is that you use for Format Strings not only to parameterize things like width and precision inside that Format String, but also as parameters like you normally would provide values.

You can get very close to using a width of 8 and a precision of 2, like the example in your question.

For instance, to quote the documentation:

Format ('%*.*f', [8, 2, 123.456]);

is equivalent to:

Format ('%8.2f', [123.456]);

That is a much overlooked feature of Format and Format Strings.
