Odd Admin area slowdown with 1.5.1 (solved)

[moorezilla]

This was all a function of "Check for new CMS versions using this URL:" in the global settings. Once I put "none" in the url field, the delay went away altogether, so I guess this delay was all a function of cmsms not being able to call home and then completing the page build once its attempt to call home timed out.


Ok... this is odd. I upgraded 1.4.1 to 1.5 and then to 1.5.1 yesterday, and all was working fine including the admin area. But today, though the site is working fine from the public side, the admin area is running terribly slow and even timing out on occasion. I don't think it's a mysql or a php issue in general, because there's nothing of note in the apache error log and I have several other php/mysql scripts running on the server that are not experiencing the same slowdown. Also... if I switch back to the 1.4.1 version of cmsms, the admin area works fine.

Apache error log pertaining to cmsms:

Other steps taken: clear cookies, restart client machine, restart apache, restart entire server, clear cmsms cache, remove tagcloud plugin that was firing errors, removed module manager, tinymce, nuSoap, and thememanager modules.

Again... I'm really at a loss for an explanation, because the admin area was working fine, but now it's really slow. To my knowledge, I haven't changed anything of note, certainly nothing that I can imagine having an effect on the admin area performance.

Anyone else running into a really slow admin area since upgrading to 1.5.1? I'm really at a loss to explain it, especially since the site (other than the admin area) is running very fast and without incident. Any ideas? Anything about the new security settings in the admin area that might cause a significant slowdown over time?

Thanks,
am
