Speed issue

Hello... We are trying to build a site using Pier. Recently we migrated to pharo0.1-10268web09.04.1. Previously we used something like Pier 1.1 with some updates. We found new version a bit slower on our computers. It was not a big problem. But we have to use an old notebook for entering data to our site. And there we've got about a minute delay after structure addition. I found the cause is in PRChangeCommand >> updateRoot: There a big string is being built started with "EditorEnh.linkOptions=". In our case it's size is 207328. Then it's being modified by copyReplaceAll: '"' with: '\"' . On old notebook it's very slow. I replaces that #copyReplaceAll:with: with (sorry for the tautology) streaming. Now it takes about 10 seconds instead of a minute. But still it's too slow (10 -- 15 seconds was a time to enter the whole data item in old image). Can this issue be fixed somehow? TIA Btw, is issues with filenames (I've asked about some time ago) fixed? -- Dennis Schetinin
