I have read through these post eagerly! I have just started using word-press and I am surprised at how slow the site is when I am uploading posts and images. I have wait times of over a minute at times for saving a post as a draft, publishing a post and even previewing it.

Uploading an image can take up to 1 minute for the interface to provide me with the upload screen once I have clicked the 'upload an image' button.

When undertaking these actions, my Mac is running hot! I can hear the fan starting up and the CPU activity and processing requirements for my browser go through the roof!!

I am running a Mac Book Pro with Chrome.

This certainly does not feel right. Can anyone help out - I am sure I have not provided all the information needed - happy to!!!

Thanks
Piero

I could not figure out how to do a running log, so I did a series that may identify the problem. The link to the screen shots are at http://www.bcphotoadventures.com/WordPress.php This was done several days ago. Again, this was not an issue before the redesign of last November.

Many thanks for your input and suggestions.

When we transfer data on internet we send it around in packets. MTU determines size of such packets. s2.wordpress.com and other hosting providers have large MTU. When receiving packets from these sites your machine tries to chop the packet up in smaller packets, or just drops the packet.

When you say "it took over 60 seconds for the Update button to react", do you mean it took 60 seconds before the Update button was available, or 60 seconds after you clicked on it?

Specifics:

When I did a short edit on an already-published blog, it took over 60 seconds for the Update button to react, and 1:22 seconds before it completed its update.

With the Edit button, it took 2 clicks and 58 seconds before it even reacted. There were things like pixel.quantserve.com, maps.google.com, maps.gstatic.com, etc., and other items that don't seem to have anything to do with the blog being read/loaded. It took another 2:02 seconds until is said "Done" in the lower right of the status bar, but I could not actually access the post to edit it until 2:37 seconds had passed.

Even though "Done" is noted in the status bar, wordpress hangs up Firefox for well over 60 seconds.

I finally did a test of exactly how long it took to do a very quick, cut-and-paste edit, and from beginning to end, including making sure it published properly, it took over 6 minutes.

As noted above, I clean out my cache regularly (several times a day), and this is the only website with which I am having speed/slug issues. Others have also noted that it never used to be this way, but last November, when the "new and improved" WordPress came out, it did something dreadful to the speed.

Any help you can give would be ever so much appreciated. It was a little teeny better for a while after the last round of exchanges, but it has reverted and apparently gotten worse.

Many thanks, I hope

I'm doing what tellyworth said and give it a try. If I can do that traceroute thing , can I post the result here ? Or do I have to open a new Threat to do so ?

Thank you.

I am very computer conversant, and while I don't know how to do a traceroute, I can't believe it's rocket science if I'm just given directions.

Google Gears is not part of my Add Ons; I checked.

I did the about:config, and there were no browser.cache items in bold.

Thank you for your trying to help. I'll wait for the traceroute directions.

1. In Firefox Tools / Extensions (or Add Ons) - if Google Gears is present, disable it.

2. In the URL bar, type about:config and scroll down to the items starting with 'browser.cache'. If any of those items are shown in bold, right-click it and choose Reset.

Went to edit posts. s2.wordpress.com and maps.gstatic.com took a long time to load, over a full minute.

Went to edit a specific post. It took 88 seconds before I could actually start editing.

On another pass, it took over 80 seconds, much of it waiting for maps.google.com.

Another time, it was 89 seconds, much of it taken up with polldaddy ratings to load.

Another time, secure.quantserve.com brought the total waiting time to 93 seconds.

"(1) You can reduce the number on the front page this way:
> Settings > Writing
Blog pages show at most __ posts
change the number and the click "Save Changes" "

I have no <b>Blog pages show at most ___ posts</b> choice.

Thank you for your input thus far.. The problem comes when I have authored part of my blog, then press Update. I am in the latest version of Firefox, and no, going to IE is NOT an option! Firefox wasn't the issue last fall, so I suspect it is something within WP.

Sorry for the delay. I've been preparing for a couple of workshops, and I realized Ihave to check in to see if there are any responses. Mea culpa!

I am not doing anything different from what I did last fall, except for perhaps a different widget (don't know which one it might be). I have been bringing my images over from my own website, just as I did before when WP was so much faster, so that can't be the issue.

When I click on Edit, it takes nearly a minute for the Edit link to show up and be functional. It shoes up reasonably quickly, but certainly not at the speed one used to see on WP, but you cannot click on it and have anything happen for about a minute.

When I just clicked on Add New, Firefox hung up. I could not go to another tab, even though "Done" was noted in the lower left of the browser. Then it frees up.

One of the messages down in the lower left starts off with or contain such verbiage as:

Waiting for s2.wordpress.com (35 seconds)
waiting for maps... (what maps? and why?)

I started a new blog, then clicked on Save Draft. Nothing happened the first time, and I do know how to click my mouse. Only WP gives me a problem (and I've been at computers since the early 80s, so I'm not an ingenue).

After about ten seconds, I click again, then after quite a few seconds saw connected maps.google.com. That lasted over 38 seconds, and from the first clicking on Safe Draft to full functionality again (remember Done does NOT mean Done), it took one minute and 18 seconds. That is not acceptable in my book.

Done is not really done for another 15 seconds or so, and anytime wordpress is doing its thing, It freezes up Firefox, and I cannot go to another tab. Again, this is the only website that has this effect ... not banking, not PayPal, not other forums, etc. while I'm waiting.

As noted above in an earlier post, I clear out my cache regularly. Again, I'm not doing anything different from last fall.

Many thanks, I hope.

What about this maps.google.com? What does that have to do with my blog?

I appreciate any insights and help that anyone can bring.

Please do not haul every thread on this topic out of the searchbox and post the same thing into them. One thread is sufficient.

I understand that we need to be specific but it seems that the problem is inside wp-admin

Thanks in advance for any hints!
